Description

S-Benzyl-Dl-Homocysteine is a protected derivative of the sulfur-containing amino acid homocysteine, widely utilized as a key chiral building block and intermediate in organic synthesis. Its primary value lies in enabling the controlled introduction of the homocysteine moiety into more complex molecular architectures, particularly in pharmaceutical research and development. This compound is essential for researchers and manufacturers in the fields of peptide chemistry, asymmetric synthesis, and the development of novel pharmaceutical actives and biochemical tools.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of cysteine protease inhibitors, cardiovascular drugs, and other bioactive molecules targeting metabolic pathways.
• Peptide Synthesis: Used as a protected amino acid derivative for the solid-phase or solution-phase synthesis of peptides and peptidomimetics, where the benzyl group safeguards the thiol functionality.
• Biochemical Research: Serves as a standard or reagent in studies related to homocysteine metabolism, oxidative stress, and enzymatic processes involving sulfur amino acids.
• Asymmetric Catalysis & Chiral Pool: Provides a source of chirality for the construction of complex, enantiomerically pure compounds in medicinal chemistry.
• Ligand and Chelator Development: Utilized in the design of novel ligands for metal catalysis or chelating agents due to its sulfur donor atom.
