Description

(S)-4-Bromo-3-Hydroxybutyric Acid Ethyl Ether is a high-value chiral building block and key intermediate in organic synthesis. This compound matters for its role in constructing complex molecules with defined stereochemistry, which is critical for developing active pharmaceutical ingredients (APIs) and advanced materials. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries for the production of enantiomerically pure compounds.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of β-blockers, statins, and other bioactive molecules requiring the (S)-configuration.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides where specific stereochemistry enhances efficacy and reduces environmental impact.
• Fine Chemical Production: Serves as a precursor for specialty chemicals, flavors, fragrances, and advanced polymer materials.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in the development of new catalytic asymmetric reactions.
• Bioconjugate Chemistry: Utilized for introducing functional handles into biomolecules due to its reactive bromo and hydroxy groups.
