Description

Pentanal, 3-Hydroxy-4-Oxo-, (S)- (9Ci) is a high-purity, chiral aldehyde derivative that serves as a critical chiral building block and intermediate in advanced organic synthesis. Its defined stereochemistry and reactive functional groups make it a valuable precursor for synthesizing complex molecules with specific optical activity. This compound is essential for research and development chemists in the pharmaceutical, agrochemical, and fine chemical industries who require enantiomerically pure intermediates for creating active ingredients and novel materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in neurological and metabolic disorder research.
• Agrochemical Synthesis: Used in the development of advanced, stereospecific pesticides and herbicides where biological activity is dependent on molecular configuration.
• Fine Chemical Production: Serves as a building block for fragrances, flavors, and other specialty chemicals requiring specific stereochemistry.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in the development and testing of new asymmetric catalytic reactions.
• Biochemical Research: Used in studies involving enzyme mechanisms and as a precursor for synthesizing chiral probes or inhibitors.
• Material Science: Potential intermediate for creating chiral polymers or liquid crystals with specific optical properties.
