For any B2B buyer in the chemical industry, particularly those in sensitive sectors like flavors, fragrances, and pharmaceuticals, the quality assurance and precise specifications of the chemical products they source are non-negotiable. Methyl Linolenate (CAS 7361-80-0), a C18:3 fatty acid methyl ester, is no exception. Understanding what to look for in terms of quality and specifications from a manufacturer is crucial for ensuring consistent performance and regulatory compliance.

The Importance of Purity in Methyl Linolenate

Methyl Linolenate is characterized by its specific molecular structure, C19H32O2, and a molecular weight of approximately 292.46 g/mol. The key differentiator in its quality is its purity, typically specified as a percentage. For applications in the flavor and fragrance industry, even minor impurities can significantly alter the scent or taste profile. Similarly, in chemical synthesis, impurities can lead to unwanted side reactions or reduce the yield and purity of the final product. Therefore, buyers should always prioritize suppliers who provide high-purity Methyl Linolenate, commonly specified as 98% or 99% by methods like Gas Chromatography (GC).

Key Specifications to Verify

When procuring Methyl Linolenate, buyers should look for a comprehensive Certificate of Analysis (CoA) that details the following:

  • CAS Number: 7361-80-0, ensuring the correct chemical identity.
  • Chemical Name: Methyl 9,12,15-octadecatrienoate and relevant synonyms.
  • Molecular Formula: C19H32O2.
  • Molecular Weight: Approximately 292.46.
  • Appearance: Typically described as a white powder or crystalline solid at room temperature.
  • Purity: Stated as a minimum percentage (e.g., ≥98% or ≥99%), usually determined by GC.
  • Other Analytical Data: Depending on the supplier, information such as refractive index, density, and residual solvent content might be provided.

Quality Assurance Processes from Manufacturer to Buyer

The journey of Methyl Linolenate from raw material to the buyer's facility involves several quality assurance checkpoints:

  1. Raw Material Inspection: Ensuring the quality of incoming linolenic acid or precursor oils.
  2. In-Process Control: Monitoring critical parameters during esterification to maintain reaction efficiency and purity.
  3. Final Product Testing: Comprehensive analysis of the finished Methyl Linolenate batch against established specifications.
  4. Packaging and Handling: Proper packaging to maintain product integrity during storage and transit, often in sealed containers to prevent contamination or degradation.
  5. Documentation: Providing accurate and complete documentation, including CoAs and Safety Data Sheets (SDS).

For businesses looking to buy Methyl Linolenate, selecting a supplier with a demonstrated commitment to quality assurance is paramount. This not only ensures product performance but also safeguards against potential production issues and regulatory non-compliance.
