Description

Methyl 2-Hydroxy-4-(Methylsulfanyl)Butanoate is a versatile sulfur-containing ester with a chiral hydroxyl group, making it a valuable chiral building block and intermediate in advanced organic synthesis. This compound is particularly significant for its role in the production of flavor and fragrance ingredients, pharmaceutical intermediates, and agrochemicals. It is essential for R&D chemists and production managers in the flavor & fragrance, pharmaceutical, and fine chemical industries seeking high-purity intermediates for complex syntheses.

Application

• Flavor and Fragrance Industry: A key intermediate in the synthesis of sulfur-containing flavor compounds, such as those imparting meaty, savory, or tropical fruit notes.
• Pharmaceutical Intermediates: Serves as a chiral synthon for the development of active pharmaceutical ingredients (APIs), leveraging its hydroxy and thioether functional groups.
• Agrochemical Synthesis: Used in the research and production of novel pesticides and herbicides where the methylsulfanyl moiety is a critical structural component.
• Fine Chemical Manufacturing: Acts as a building block for specialty chemicals, including ligands for catalysis and monomers for functional polymers.
• Nutritional Supplements: Potential intermediate in the synthesis of precursors for sulfur-containing amino acids or related nutraceuticals.
• Organic Synthesis Research: A valuable substrate for methodological development in asymmetric synthesis and green chemistry applications.

Quality Control

Our Methyl 2-Hydroxy-4-(Methylsulfanyl)Butanoate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for fine chemical and intermediate applications. Certificates of Analysis (COA) documenting purity, enantiomeric ratio (if applicable), and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
