Description

(S)-2-Methylhexanoic Acid is a high-purity chiral carboxylic acid, a key building block in asymmetric synthesis. Its defined stereochemistry is critical for producing enantiomerically pure compounds, ensuring superior efficacy and safety in advanced applications. This material is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where precise molecular architecture dictates product performance.

Application

• Pharmaceutical Intermediates: A crucial chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in cardiovascular and central nervous system (CNS) drugs.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides and pesticides, where the specific (S)-enantiomer often provides the desired biological activity.
• Flavor and Fragrance Industry: Serves as a precursor for chiral esters and lactones that contribute to sophisticated, natural-tasting flavor profiles and unique fragrance notes.
• Ligand and Catalyst Development: Employed in the research and manufacture of chiral ligands and organocatalysts for asymmetric catalysis.
• Advanced Material Research: Acts as a monomer or modifying agent in the synthesis of polymers with specific chiral properties for specialized coatings and electronics.
• Chemical Reference Standard: Used as a high-purity standard in analytical laboratories for method development and quality control of chiral compounds.

Quality Control

Every batch of (S)-2-Methylhexanoic Acid is produced under strict quality management systems. We provide comprehensive analytical data to ensure the product meets the high standards required for chiral synthesis. Certificates of Analysis (COA) detailing identity, purity (by GC/HPLC), enantiomeric excess (ee), and impurity profiles are available for each lot. Our quality commitment supports compliance in cGMP and ISO 9001 environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent, store separately from incompatible materials such as strong bases, oxidizing agents, and amines.
