Description

Benzoic Acid, 4-[1-Methyl-2-(1-Oxobutoxy)Ethyl]-, (+)- (9Ci) is a specific, high-purity chiral derivative of benzoic acid, characterized by its butyryloxy ester side chain. This compound matters as a valuable chiral building block and intermediate for the synthesis of more complex molecules in advanced research and development. It is needed by pharmaceutical, agrochemical, and fine chemical industries for applications requiring enantiomerically pure intermediates, such as in the development of active pharmaceutical ingredients (APIs) and specialty chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel Active Pharmaceutical Ingredients (APIs), particularly for central nervous system (CNS) or metabolic disorder drugs.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, or plant growth regulators where specific stereochemistry is crucial for bioactivity.
• Fine Chemical Manufacturing: Acts as a specialized intermediate for synthesizing complex fragrances, flavors, or liquid crystals that require precise stereochemical control.
• Academic & Industrial R&D: Employed in chemical research for studying asymmetric synthesis, catalysis, and the structure-activity relationships (SAR) of chiral molecules.
• Process Chemistry Development: Utilized for scaling up and optimizing synthetic routes for commercial production of high-value chiral compounds.
