The molecular weight of the compound is 152.15, a constant value used in stoichiometric calculations for downstream manufacturing processes. Buyers must ensure that the supplier's technical data sheet aligns with these specific numerical ranges to avoid process failures in their own production lines.

Regulatory Compliance and Certification Verification

When sourcing methyl salicylate for applications in cosmetics, balms, and synthesis, regulatory compliance is non-negotiable. The material is often associated with standards such as the British Pharmacopoeia (BP) and the United States Pharmacopoeia (USP), with specific model numbers like Methyl Salicylate BP/USP appearing in product listings. The European Inventory of Existing Commercial Chemical Substances (EINECS) number 1437450 is a key identifier for regulatory tracking in international trade.

Buyers must verify that the supplier can provide documentation confirming adherence to these pharmacopoeial standards. While the product may be labeled as "Technical" grade in some contexts, applications in cosmetics and pharmaceuticals often require higher grades. The presence of the EINECS number and specific USP/BP references suggests a level of regulatory recognition, but the buyer must confirm that the specific batch being purchased meets the current edition of these standards. Heavy metal content is a significant compliance factor, with observed maximum limits set at 0.002% (20ppm). Ensuring that the supplier's quality control processes can consistently meet this limit is essential for regulatory approval in sensitive markets.

Additionally, the classification of the material as a "High Purity Material" and its use in "Synthesis" imply that the supply chain must be transparent regarding the origin and processing methods. The product origin is frequently cited as Liaoning, China, a major industrial hub for chemical production. Buyers should verify that the "Place of Origin" on the commercial invoice matches the certification documents provided. The distinction between "Technical" and "Standard" quality grades should be clearly defined in the purchase order to prevent the receipt of sub-standard materials that could compromise final product safety.

Cost Drivers and Pricing Dynamics

The pricing of methyl salicylate is influenced by several dynamic factors, including raw material costs, energy prices, and global supply chain logistics. The observed price range in the market spans from 2 to 3500 USD, a wide variance that reflects differences in purity levels, packaging formats, order volumes, and supplier positioning. This broad range indicates that the commodity is available in various tiers, from bulk industrial grades to highly refined, small-batch pharmaceutical grades.

The Minimum Order Quantity (MOQ) is a significant cost driver, with observed ranges from 1 kg to 1000 kg. Suppliers offering lower MOQs, such as 1 kg, often charge a premium per unit due to the logistical overhead of handling smaller shipments. Conversely, larger orders, potentially up to 1000 kg, may benefit from economies of scale, though the total capital outlay is higher. The supply ability of major suppliers is reported at 150 metric tons per month, suggesting that large-volume buyers can secure consistent supply, but smaller buyers may face constraints or higher unit costs.

Packaging also impacts the final cost. The standard packaging is often listed as 25 kg per drum, with single package dimensions of 37x37x45 cm and a gross weight of 28.000 kg. Customization is available, which can alter the price structure. Buyers must evaluate whether the cost of custom packaging or smaller unit sizes justifies the operational benefits for their specific inventory management needs. The selling unit is typically a single item, but bulk pricing structures should be negotiated based on the total volume required.

Typical Applications and End-Use Markets

Methyl salicylate serves as a versatile intermediate in multiple industries, with its primary applications driving demand and specification requirements. One of the most prominent uses is in the formulation of balms, where its characteristic aroma and therapeutic properties are highly valued. The application field explicitly lists "Balm" as a primary use case, indicating its role in topical analgesic products. In the cosmetics sector, it is utilized for its fragrance profile and potential skin benefits, necessitating high purity and strict heavy metal limits.

Beyond personal care, the material is a crucial intermediate in chemical synthesis. It is classified under "Syntheses Material Intermediates," suggesting its use as a building block for more complex molecules in the pharmaceutical and agrochemical sectors. The specific usage is often noted as "For Synthesis," highlighting its role as a reactant rather than a final consumer product in many contexts. The chemical's properties, such as its water solubility of 0.07 g/100 mL at 20 °C, make it suitable for oil-based formulations and specific extraction processes.

The versatility of methyl salicylate extends to its classification as a "Flavor & Fragrance Intermediate," where it provides a wintergreen scent profile. This dual utility in both therapeutic balms and fragrance formulations requires suppliers to maintain strict quality controls to ensure the material meets the diverse needs of different end-users. Buyers should clearly define the intended application in their procurement specifications to ensure the supplier provides the correct grade of methyl salicylate.

Supplier Evaluation and Logistics Management

Selecting a reliable supplier for methyl salicylate requires a thorough evaluation of their operational capabilities and logistical infrastructure. The port of dispatch is a critical factor, with Dalian frequently cited as the primary shipping point for this commodity. Buyers should verify that the supplier has established logistics channels from Dalian to their destination, considering the transport machine options, which typically include ordinary goods trucks for domestic or regional distribution.

The shelf life of the product is another key evaluation criterion. Observed shelf life data indicates a duration of greater than 12 months, with some sources citing a self-life of 2 years. This longevity is advantageous for inventory planning, but buyers must ensure that the packaging, typically blue drums made of plastic, is robust enough to maintain product integrity over this period. The packaging material must be compatible with the chemical to prevent degradation or leakage.

Supplier reliability is also gauged by their customization capabilities. The availability of customization options suggests a flexible supply chain that can adapt to specific buyer requirements. However, buyers must assess the lead times associated with customized orders versus standard stock.
