Description

Mercaptosuccinic Acid, Sodium Salt is the sodium salt derivative of mercaptosuccinic acid, a versatile organosulfur compound. This product is valued for its role as a key intermediate and reagent in organic synthesis and pharmaceutical manufacturing, offering enhanced water solubility and handling stability. It is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for applications requiring a thiol-functionalized building block.

Application

• Pharmaceutical Intermediate: Acts as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing thiol or disulfide functionalities.
• Biochemical Research: Used as a reducing agent or a sulfhydryl group donor in biochemical assays and protein chemistry studies.
• Polymer Modification: Serves as a chain transfer agent or a functional monomer to introduce thiol groups into polymers, modifying their properties.
• Hair Care & Cosmetic Formulations: Employed in the production of certain hair perming and straightening agents due to its ability to break and reform disulfide bonds in keratin.
• Agrochemical Synthesis: Utilized as an intermediate in the manufacture of certain herbicides and fungicides.
• Metal Chelation & Surface Treatment: Functions as a ligand for metal ions or in formulations for metal surface treatment and plating processes.

Quality Control

Our Mercaptosuccinic Acid, Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with every shipment to guarantee it meets your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers should be kept tightly sealed under an inert atmosphere after opening to minimize exposure to air and moisture.
