Description

Propanoic Acid, 2-Hydroxy-, Propyl Ester, (2R)- (9Ci) is a specific stereoisomer of propyl lactate, a chiral ester derived from lactic acid. This high-purity, optically active compound is critical for applications requiring precise stereochemistry and controlled reactivity. It serves as a valuable chiral building block and intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors, where enantiomeric purity directly impacts product efficacy and safety.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in developing enantiomerically pure drugs.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides, where the specific (R)-configuration can be essential for biological activity.
• Flavor and Fragrance Ingredient: Employed as a precursor for esters that contribute fruity or buttery notes in advanced flavor formulations.
• Polymer and Resin Modifier: Acts as a reactive monomer or plasticizer component in the synthesis of biodegradable polymers like polylactic acid (PLA) derivatives.
• Organic Synthesis Reagent: Serves as a protected or activated form of lactic acid for asymmetric synthesis and esterification reactions in fine chemical production.
• Solvent and Carrier: Utilized as a high-boiling, "green" solvent for specialized coatings, inks, and resin applications due to its favorable environmental profile.
