Description

2-Hydroxy-n-Butyric Acid Ethyl Ester is a versatile chiral building block and ester derivative of 2-hydroxybutyric acid. This compound matters for its utility as a key intermediate in the synthesis of complex molecules, particularly in the pharmaceutical and fine chemical industries. It is needed by R&D chemists and production facilities engaged in creating active pharmaceutical ingredients (APIs), agrochemicals, and specialty flavors or fragrances.

Application

• Pharmaceutical Intermediate: A crucial chiral synthon for the production of various active pharmaceutical ingredients (APIs) and drug candidates.
• Agrochemical Synthesis: Used in the manufacturing of advanced pesticides and herbicides where specific stereochemistry is required.
• Flavor and Fragrance Ingredient: Serves as a precursor for esters that contribute to fruity or buttery flavor and aroma profiles.
• Polymer Modification: Acts as a monomer or co-monomer in the synthesis of specialized biodegradable or functional polymers.
• Organic Synthesis Reagent: Employed in asymmetric synthesis, esterification reactions, and as a protecting group in multi-step synthetic routes.
• Solvent and Plasticizer: Functions as a high-boiling-point solvent or a plasticizer in specific industrial formulations.
