Description

2-Pentanone, 3,4-Dihydroxy-, [S-(R*,S*)]- (9Ci) is a chiral dihydroxy ketone, a valuable building block in asymmetric synthesis. Its defined stereochemistry makes it a critical intermediate for the production of complex, optically active molecules where precise spatial orientation is essential. This compound is primarily sought by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug molecules, particularly in anti-infective and cardiovascular research.
• Asymmetric Catalysis Research: Used as a precursor or ligand in the development of new catalytic systems for stereoselective reactions.
• Agrochemical Synthesis: Serves as a building block for creating advanced, enantiomerically pure herbicides and pesticides.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances requiring high stereochemical purity.
• Academic & R&D Laboratories: Utilized in methodological studies and the exploration of new synthetic pathways in organic chemistry.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide high-purity grades suitable for research and synthesis, with identity and purity confirmed by advanced analytical techniques. Certificates of Analysis (COA) detailing chiral purity, chemical purity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere to prevent degradation.
