Description

n-Acetyl-2-Mercapto-Dl-Alanine is a chemically modified derivative of the amino acid alanine, featuring both acetyl and thiol (mercapto) functional groups. This unique structure makes it a valuable intermediate and building block for synthesizing more complex molecules in pharmaceutical and biochemical research. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring a protected cysteine analog or a thiol-containing synthon.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring thiol or disulfide linkages.
• Biochemical Research: Used as a precursor or substrate in enzymatic studies and for the preparation of modified peptides and proteins.
• Agrochemical Synthesis: Serves as an intermediate in the development of novel herbicides, fungicides, and plant growth regulators.
• Chelating Agent Precursor: Utilized in the production of ligands and chelating agents due to its thiol group's affinity for metal ions.
• Cross-linking Agent: Acts as a starting material for synthesizing cross-linkers used in polymer chemistry and material science.
• Reference Standard: Employed as an analytical standard in quality control laboratories for method development and validation.
