Description

Benzaldehyde, 4-[(1S)-1-Hydroxyethyl]- (9Ci) CAS NO 212696-86-1 is a chiral aromatic aldehyde derivative, characterized by a hydroxymethyl group at the para position of the benzaldehyde core. This compound is a valuable chiral building block and intermediate in fine chemical synthesis, prized for its defined stereochemistry which is critical for producing enantiomerically pure products. It is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and advanced material sectors for developing active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and cardiovascular drug research.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides, where specific stereochemistry can enhance efficacy and reduce environmental impact.
• Flavor & Fragrance Precursor: Serves as a starting material for the synthesis of complex aromatic compounds used in high-value perfumery and flavoring agents.
• Ligand & Catalyst Development: Employed in the research and manufacture of chiral ligands and organocatalysts for asymmetric synthesis.
• Advanced Material Research: Acts as a monomer or functionalization agent in the development of specialty polymers and liquid crystals.
• Academic & R&D: A standard reagent in university and corporate laboratories for methodological studies in organic and medicinal chemistry.
