The product scope for refined TBAB encompasses its role as a synthesis material intermediate and a dye intermediate, with applications extending to catalysis and ion-pair reagent functions. Observed listings describe the product as a white powder with a melting point range of 102-106 °C and a boiling point of 102°C, although buyers should treat these as observational data points requiring confirmation. The presence of brands like Qinmu and bosschemical, along with supply types including OEM/ODM, indicates a competitive market with multiple manufacturing sources. Buyers should interpret these signals as evidence of availability but must verify that the specific batch meets the purity standards required for homogeneous catalysis, which often demands higher precision than general industrial grades.

Packaging and logistics signals from the listings vary, with options including 1kg/bag, 25kg/drum, and smaller units like 100g or 25g. This flexibility supports different procurement scales, from pilot projects to full-scale production. The stated origin is primarily China, with specific mentions of Shandong as a place of origin, which is a known hub for chemical manufacturing. Buyers should note that while free samples are supported by some suppliers, the delivery time is cited as 3-5 days, which may vary based on location and customs procedures. Understanding these logistical parameters is essential for planning inventory and ensuring that the catalyst arrives in suitable condition, given the requirement for room temperature storage.

Technical Specifications to Verify

Verification of technical specifications is paramount when sourcing TBAB for catalytic applications. The primary attribute to confirm is the purity level, with observed listings citing 99% purity and a 99% minimum assay. Buyers must request a Certificate of Analysis (CoA) that explicitly states the assay percentage and confirms the absence of impurities that could inhibit catalytic activity. The physical form is consistently described as a solid white powder, but buyers should verify the particle size distribution if their process requires specific dissolution rates. Additionally, the refractive index of 1.039 and molecular weight of 322.37 are listed, but these values should be cross-referenced with standard chemical databases to ensure accuracy, as discrepancies in the provided data suggest a need for independent validation.

Chemical identity verification must include confirmation of the CAS number 1941-30-6 and the molecular formula C12H28BrN. Buyers should be cautious of listings that mention conflicting names, such as Tetrapropylammonium bromide, which has a different chemical structure and properties. The melting point range of 102-106 °C is a key identifier, and any deviation from this range could indicate contamination or a different compound. Furthermore, the storage condition is specified as room temperature, but buyers should inquire about the stability of the product over time and whether any special handling is required to prevent degradation or moisture absorption, which could affect its performance as a homogeneous catalyst.

Compliance and Safety Documentation

Compliance and safety documentation form the backbone of responsible procurement for chemical intermediates. The observed listings mention ISO 9001 certification, which indicates a quality management system but does not guarantee product-specific compliance. Buyers must request additional safety data sheets (SDS) that detail the handling, storage, and disposal requirements for TBAB. Given its use as a catalyst and ion-pair reagent, understanding the potential hazards, such as skin irritation or environmental impact, is crucial for maintaining workplace safety and regulatory compliance. The absence of explicit hazard classifications in the provided data underscores the need for buyers to obtain comprehensive safety information from the supplier before placing an order.

Regulatory compliance extends to environmental and trade regulations, particularly when sourcing from international suppliers. Buyers should verify that the supplier adheres to relevant chemical regulations in both the country of origin and the destination country. This includes checking for compliance with REACH, TSCA, or other local chemical management laws. The EINECS number 217-727-6 is a positive indicator for European market compliance, but buyers must ensure that the product is registered and that the supplier provides necessary documentation for customs clearance. Additionally, buyers should inquire about the supplier’s waste management practices and whether they offer guidance on the safe disposal of TBAB residues, which is essential for maintaining environmental stewardship.

Cost Drivers and Commercial Terms

Cost drivers for refined TBAB include the purity level, packaging size, and order volume. The observed price range of 1-600 USD suggests significant variation based on these factors, with smaller quantities likely commanding a higher per-unit cost. Buyers should analyze the total cost of ownership, including shipping, insurance, and potential tariffs, rather than focusing solely on the unit price. The availability of free samples can reduce initial testing costs, but buyers should be aware that sample quality may not always reflect bulk production standards. Negotiating volume discounts and establishing long-term contracts can help stabilize costs and ensure supply continuity.

Commercial terms such as MOQ, lead time, and payment terms are critical components of the procurement strategy. The observed MOQ range of 1-25 units offers flexibility, but buyers should consider the economic order quantity that balances inventory holding costs with procurement frequency. The stated delivery time of 3-5 days is attractive, but buyers should verify this claim with the supplier and understand the factors that could cause delays, such as production bottlenecks or logistical issues. Payment terms should be negotiated to mitigate risk, with options such as letters of credit or escrow services providing security for both parties. Clear communication regarding these terms helps prevent misunderstandings and ensures a smooth transaction process.

Supplier Qualification and Quality Control

Supplier qualification is a multi-step process that begins with verifying the supplier’s legal status and manufacturing capabilities. Buyers should request evidence of the supplier’s ISO 9001 certification and inquire about their quality control procedures, including in-process testing and final product inspection. The presence of OEM/ODM supply types suggests that the supplier has the flexibility to meet specific customer requirements, but buyers must ensure that these customizations do not compromise product quality. Visiting the supplier’s facility or conducting third-party audits can provide valuable insights into their operational standards and commitment to quality.

Quality control measures should include regular testing of incoming TBAB batches to ensure consistency and compliance with specifications.
