Description

(S)-3-Amino-4-(4-Bromophenyl)Butanoic Acid Hydrochloride is a high-purity chiral building block and pharmaceutical intermediate. This compound is valued for its role in the synthesis of complex molecules, particularly in medicinal chemistry where its defined stereochemistry and functional groups are critical. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of new active pharmaceutical ingredients (APIs) and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel therapeutic agents, particularly for central nervous system (CNS) targets.
• Peptidomimetics Synthesis: Used in the construction of peptide analogs and mimetics due to its amino acid-like structure with a bromophenyl side chain.
• Asymmetric Catalysis Research: Serves as a valuable substrate or ligand precursor in studies of asymmetric synthesis and chiral catalysis.
• Chemical Biology Probes: Employed in the design and synthesis of molecular probes for studying biological pathways and protein interactions.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis projects requiring high stereochemical purity and reliable supply.
