Description

L-Aspartic Acid, 3-Mercapto- (9Ci) is a specialized, sulfur-containing derivative of the amino acid L-aspartic acid. This compound is valued for its unique thiol functional group, which makes it a versatile building block in advanced organic synthesis and pharmaceutical research. It is particularly relevant for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries seeking to develop novel compounds with specific biological activity or chelating properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting enzyme inhibition or requiring metal chelation.
• Peptide Synthesis: Used as a modified amino acid residue to introduce thiol functionality into peptides and proteins for structure-activity relationship (SAR) studies or bioconjugation.
• Agrochemical Research: Serves as a building block for developing new active ingredients in herbicides, fungicides, or plant growth regulators.
• Biochemical Research: Employed in studies of enzyme mechanisms, metabolic pathways, and as a ligand in coordination chemistry due to its carboxylate and thiol groups.
• Chelating Agent Precursor: Useful in the development of specialized chelating agents for metal ion sequestration or catalysis.
• Fine Chemical Synthesis: A versatile chiral synthon for the asymmetric synthesis of complex organic molecules in academic and industrial R&D settings.

Quality Control

Our L-Aspartic Acid, 3-Mercapto- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC), chiral purity, and related substances are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed after each use to minimize exposure to air.
