Description

Alanine, n-(2-Mercaptoethyl)-, Methyl Ester (9Ci) is a specialized, sulfur-containing amino acid derivative. This compound matters as a versatile chiral building block and a key intermediate for synthesizing complex molecules, particularly in pharmaceutical research and development. It is primarily needed by fine chemical manufacturers and R&D laboratories focused on peptide mimetics, drug discovery, and the development of novel bioactive compounds.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in oncology and metabolic disease research.
• Peptidomimetic Chemistry: Used to construct peptide analogs and mimetics where the thiol group provides a handle for further functionalization or cyclization.
• Ligand Synthesis: Serves as a precursor for chelating agents and ligands in catalysis and metal-binding studies.
• Bioconjugation: The reactive thiol functionality makes it suitable for creating bioconjugates and protein-drug linkers.
• Chemical Biology Probes: Employed in the development of probes for studying enzyme mechanisms and protein interactions.
• Academic & Industrial R&D: A valuable reagent for exploratory synthetic chemistry in both university and corporate research settings.
