Description

Dmsa CAS NO 4710-17-2, known chemically as Dimercaptosuccinic Acid, is a critical dithiol chelating agent. Its primary value lies in its ability to bind and facilitate the excretion of toxic heavy metals from biological systems. This makes it an essential compound for manufacturers in the pharmaceutical, research, and chemical synthesis sectors, particularly for producing chelation therapies and advanced intermediates.

Application

• Pharmaceutical Active Ingredient: Key raw material for the synthesis of Succimer, a lead and mercury chelation drug.
• Research & Diagnostic Reagents: Used in biochemical research and in-vitro diagnostic kits as a specific chelator for heavy metal ions.
• Chemical Synthesis Intermediate: Serves as a versatile building block for synthesizing more complex dithiol compounds and ligands.
• Analytical Chemistry: Employed as a complexing agent in titrations and for the selective extraction and detection of heavy metals.
• Industrial Catalyst & Stabilizer: Functions in certain polymerization processes and as a stabilizer in polymer formulations.
• Environmental & Decontamination Applications: Investigated for use in environmental remediation to bind and remove heavy metal contaminants.

Quality Control

Our Dmsa is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets high-grade specifications suitable for pharmaceutical and research applications. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere after opening to minimize exposure to moisture and air.
