Quality Control

Our Methyl 3-Mercaptobutanoate is produced under strict quality management systems. Each batch is analyzed to ensure high purity and consistency, meeting the stringent requirements of the flavor, fragrance, and fine chemical industries. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
