Description

S-Methyl-D-Penicillamine is a specialized chiral penicillamine derivative, a key building block in advanced pharmaceutical synthesis and biochemical research. Its value lies in its role as a precursor and intermediate for developing novel therapeutic agents and as a tool for studying enzyme mechanisms and metal chelation. This high-purity compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require reliable, high-quality intermediates for complex synthetic pathways.

Application

• Pharmaceutical Intermediate: Critical precursor in the synthesis of novel drug candidates, particularly those targeting rheumatoid arthritis, Wilson's disease, and heavy metal poisoning.
• Biochemical Research: Used as a chiral ligand or inhibitor in enzymatic studies and for investigating thiol-disulfide exchange reactions in biological systems.
• Chelation Therapy Studies: Serves as a research standard for developing and testing new metal-chelating agents due to its structural similarity to D-penicillamine.
• Asymmetric Synthesis: Employed as a chiral auxiliary or building block in the production of enantiomerically pure compounds for active pharmaceutical ingredients (APIs).
• Reference Standard: Utilized as a high-purity analytical standard in quality control laboratories for method development and validation.
• Fine Chemical Production: Intermediate in the manufacture of specialized chemicals for diagnostic kits and research reagents.

Quality Control

Our S-Methyl-D-Penicillamine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the stringent requirements for pharmaceutical research and development. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
