Source pharmaceuticals grade miconazole nitrate powder for APIs, Topicals, and Compounding

Miconazole Nitrate Powder Sourcing Guide

Procuring pharmaceutical-grade miconazole nitrate powder requires a disciplined approach to verifying chemical identity and purity, as the market contains variations in nomenclature and specification that can lead to procurement errors. Buyers must distinguish between the specific nitrate salt form, identified by CAS No. 22832-87-7 and molecular formula C18H15Cl4N3O4, and related miconazole variants which may possess different molecular weights or melting points. The observed listings indicate a product range where the active ingredient is consistently described as a white to almost white crystalline powder, yet the exact CAS number and molecular weight must be cross-referenced against the specific batch Certificate of Analysis (COA) to ensure the correct salt form is being sourced for pharmaceutical applications.

The commercial landscape for this material presents a wide spectrum of Minimum Order Quantities (MOQ) and pricing structures, ranging from small trial batches of 1 unit to large industrial volumes of 50,000 units. This variability suggests that suppliers cater to both research and development needs and large-scale manufacturing requirements, necessitating that buyers clarify their volume requirements early in the negotiation process. While some listings offer customizable packaging and formulations, others adhere to standard packing specifications such as 1kg per bag or 25kg per drum, and the decision to proceed with a supplier often hinges on whether their flexibility in customization aligns with the buyer's specific production or formulation needs.

Product Scope and Observed Listing Signals

When evaluating product listings, buyers should focus on the consistency of the chemical identifiers, specifically the CAS number 22832-87-7 and the molecular weight of approximately 479.14, which are critical markers for the nitrate salt form. The observed data shows that some entries list the product simply as "Miconazole" with a different CAS number (22916-47-8) and a lower molecular weight of 416.13, indicating a potential confusion between the base compound and the nitrate salt. It is essential to verify that the product name explicitly states "Miconazole Nitrate" and that the molecular formula matches C18H15Cl4N3O4 to avoid receiving the wrong chemical entity, which would render the material unsuitable for its intended pharmaceutical use.

The physical appearance and state of the powder are consistent across most high-confidence listings, described as a white to almost white crystalline powder or simply white powder in a solid state. However, buyers must be cautious of discrepancies in physical property data, such as melting points ranging from 159-163°C to other reported values, as these can indicate different grades or impurity levels. The boiling point is consistently noted around 555.1°C at 760 mmHg, but the primary visual and physical verification should rely on the COA to confirm the crystalline nature and color, ensuring the material meets the visual standards required for pharmaceutical formulation.

Technical Specifications to Verify

The purity of the material is a primary technical specification, with observed listings claiming a purity greater than 99% and a standard specification of 99%. Buyers must insist on a Certificate of Analysis (COA) that explicitly confirms the assay results using the High-Performance Liquid Chromatography (HPLC) test method, as this is the standard technique referenced for verifying the potency of the powder. Relying solely on the listed "99%" standard without a corresponding COA is insufficient, as the actual batch purity must be verified against the specific analytical data provided by the manufacturer to ensure it meets the strict requirements of pharmaceutical grade materials.

Melting point and storage conditions are critical technical parameters that influence the stability and handling of the powder during the manufacturing process. The observed melting point range of 159-163°C serves as a key identifier for the substance, and any deviation from this range in the COA could indicate degradation or the presence of impurities. Furthermore, the product is specified to have a shelf life of 2 years when stored at room temperature, and buyers should verify that the supplier's storage protocols align with these conditions to maintain the integrity of the material from the point of manufacture through to the point of receipt.

Compliance and Safety Documentation

Compliance with international pharmacopoeia standards is a non-negotiable requirement for sourcing pharmaceutical-grade miconazole nitrate, and the observed certifications include BP (British Pharmacopoeia), USP (United States Pharmacopeia), ISO, HSE, and GMP (Good Manufacturing Practice). Buyers must request current certification documents that explicitly cover the specific product model, such as HNR-Miconazole Nitrate, to ensure the manufacturing facility adheres to the rigorous quality management systems required for pharmaceutical ingredients. The presence of these certifications indicates a commitment to quality, but the validity and scope of each certificate must be confirmed to ensure they are not expired or limited to other product lines.

Safety and handling documentation must be comprehensive, including detailed Material Safety Data Sheets (MSDS) that address the specific hazards associated with the powder. While the product is suitable for use in formulations for adults, children, and the elderly, the safety data must clearly outline the risks of inhalation or contact and provide appropriate personal protective equipment (PPE) recommendations. The origin of the product, often listed as Xi'an, Shaanxi, or generally China, should be accompanied by export compliance documents that verify the material meets the regulatory requirements of the destination country, ensuring that the supply chain is transparent and legally compliant.

Cost Drivers and Commercial Terms

The cost of miconazole nitrate powder is influenced by the scale of the order, with observed MOQs ranging from 1 unit to 50,000 units, creating a significant variance in unit economics. Buyers seeking small quantities for testing or R&D may face higher per-unit costs compared to those placing large industrial orders, and the negotiation of pricing should reflect the volume commitment and the specific packaging requirements, such as 1kg bags versus 25kg drums. The flexibility of the supplier to offer customized packaging or formulations can also impact the final price, as these value-added services often incur additional processing and handling fees.

Commercial terms regarding lead times and shipping logistics are critical factors that can affect the overall cost and timeline of the procurement process. While specific lead times are not universally defined in the observed data, the variability in MOQ and the potential for customization suggest that production schedules may differ significantly between suppliers. Buyers should clarify the delivery terms, including whether the price includes packaging costs and shipping, and ensure that the agreed-upon delivery schedule aligns with their production needs to avoid costly delays or inventory shortages.

Supplier Qualification and Quality Control

Supplier qualification should begin with a rigorous review of their manufacturing capabilities and quality control systems, specifically their adherence to GMP and ISO standards. The ability of a supplier to provide a detailed COA for every batch, utilizing HPLC for testing, is a strong indicator of their quality control maturity. Buyers should verify that the supplier has a documented process for handling non-conforming products and that they maintain traceability from the raw materials to the final packaged product, ensuring that the miconazole nitrate powder meets the specified purity and physical characteristics.

The origin of the product, frequently cited as Xi'an or Shaanxi, should be verified through site audits or third-party assessments to ensure that the manufacturing environment meets international standards. Buyers should assess the supplier's capacity to handle customization requests, as some listings indicate that customization is available while others specify non-customized options. The ability to adapt packaging, such as offering 1kg per bag or 25kg per drum, and to provide specific documentation like the COA, demonstrates the supplier's flexibility and commitment to meeting the diverse needs of pharmaceutical clients.

Long-Term Procurement Checks

Establishing a long-term procurement relationship requires regular audits of the supplier's quality performance and consistency in delivering materials that meet the 99% purity standard. Buyers should implement a system for periodic re-testing of incoming batches to ensure that the melting point, appearance, and assay results remain consistent over time, as any drift in these parameters could indicate issues with the manufacturing process or storage conditions. Maintaining a robust quality assurance program helps to mitigate the risk of supply chain disruptions and ensures that the pharmaceutical products manufactured using the miconazole nitrate powder remain safe and effective.

Continuous monitoring of regulatory changes and certification renewals is essential for maintaining compliance in the long term. As pharmacopoeia standards evolve, suppliers must demonstrate their ability to adapt their manufacturing processes and documentation to meet new requirements. Buyers should establish a schedule for reviewing the supplier's certifications, such as BP, USP, and GMP, to ensure they remain valid and relevant to the specific product being sourced. This proactive approach to supplier management helps to safeguard the supply chain against regulatory risks and ensures a steady flow of high-quality miconazole nitrate powder for pharmaceutical applications.
