Description

Propanoic Acid, 2-Hydroxy-, Ethyl Ester, (R)- is the single enantiomer form of ethyl (R)-(-)-lactate, a high-purity chiral building block and solvent. This compound is essential for applications requiring stereochemical control, offering superior optical purity for advanced synthesis. It is a critical material for pharmaceutical intermediates, fine chemical synthesis, and as a specialty green solvent in high-value industries.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the production of active pharmaceutical ingredients (APIs), especially in asymmetric synthesis.
• Fine Chemical Synthesis: Used in the manufacture of agrochemicals, flavors, and fragrances where specific stereochemistry is required.
• Specialty Solvent: Employed as a biodegradable and renewable "green" solvent in coatings, electronics, and high-purity extraction processes.
• Polymer Industry: Acts as a monomer or co-monomer for producing biodegradable polymers like polylactic acid (PLA) derivatives.
• Catalyst and Ligand Preparation: Serves as a precursor for chiral ligands and catalysts used in enantioselective catalysis.
• Food & Flavor Industry: Used in the synthesis of specific flavor esters and food-grade additives (subject to appropriate grade and certification).
