Description

2-Pentanone, 3-Hydroxy-4-Methyl-, (S)- (9Ci) is a chiral, optically active ketone derivative with a hydroxyl group, making it a valuable building block for asymmetric synthesis. This compound matters for its role as a key intermediate in the production of fine chemicals and active pharmaceutical ingredients (APIs), where its defined stereochemistry is critical for biological activity. Industries such as pharmaceutical R&D, agrochemical manufacturing, and specialty fragrance synthesis need this high-purity chiral synthon to develop novel compounds with specific enantiomeric purity.

Application

• Pharmaceutical Intermediate: A crucial chiral building block for the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and production of enantiomerically pure pesticides and herbicides.
• Fine Chemical Production: Serves as a precursor in the manufacture of specialty chemicals, flavors, and fragrances.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in academic and industrial research for developing new catalytic methodologies.
• Material Science: Potential monomer or modifier in the synthesis of specialized polymers with unique optical properties.

Quality Control

Our 2-Pentanone, 3-Hydroxy-4-Methyl-, (S)- (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles are available upon request to support your regulatory and R&D needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which could affect product stability and performance.
