Description

Methyl (S)-2-Hydroxybutyrate is a high-purity chiral building block and intermediate of significant importance in asymmetric synthesis. Its defined stereochemistry makes it a valuable precursor for the production of pharmaceuticals, agrochemicals, and fine chemicals where specific enantiomeric purity is critical. This compound is essential for researchers and manufacturers in the pharmaceutical, flavor & fragrance, and advanced materials sectors seeking to develop or produce optically active molecules.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in cardiovascular and metabolic disease research.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Flavor and Fragrance Ingredient: Serves as a precursor for creating specific, high-value aroma compounds and flavorants.
• Liquid Crystal and Polymer Chemistry: Acts as a monomer or chiral dopant in the synthesis of advanced polymeric materials and liquid crystal displays (LCDs).
• Asymmetric Catalysis Research: A standard substrate or ligand precursor in academic and industrial research for developing new catalytic methodologies.
• Biochemical Research: Used in metabolic studies and as a standard for analytical method development in chiral separation techniques.
