Description

Dl-2,3-Dimercapto-1-Propanesulfonic Acid Sodium Salt Monohydrate is a water-soluble, sulfonated derivative of dimercaprol (BAL) that serves as a potent chelating agent for heavy metals. Its primary value lies in its ability to form stable, water-soluble complexes with toxic metal ions, offering a critical advantage in detoxification and analytical applications. This compound is essential for researchers and manufacturers in the pharmaceutical, environmental testing, and chemical synthesis sectors who require a reliable and effective metal-sequestering agent.

Application

• Pharmaceutical Intermediate: Used in the research and development of chelation therapy drugs for heavy metal poisoning (e.g., arsenic, mercury, lead).
• Analytical Chemistry Reagent: Serves as a complexing agent in spectrophotometric and electrochemical methods for the detection and quantification of trace metals.
• Biochemical Research: Employed in studies of metalloenzymes and metal-protein interactions due to its specific affinity for soft metal ions.
• Environmental Remediation: Investigated for use in processes designed to remove or recover heavy metal contaminants from wastewater and soil.
• Chemical Synthesis: Acts as a protecting group or catalyst in organic synthesis reactions involving sulfur chemistry or metal catalysis.
• Reference Standard: Utilized as a high-purity standard in quality control laboratories for method validation and calibration.

Quality Control

Our Dl-2,3-Dimercapto-1-Propanesulfonic Acid Sodium Salt Monohydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade specifications suitable for research and industrial use. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maximize shelf life and maintain purity.
