Description

Thioglycolic Acid CAS NO 68-11-1 is a versatile organosulfur compound characterized by its mercapto and carboxylic acid functional groups. This dual functionality makes it a critical intermediate and reagent in numerous industrial and fine chemical synthesis processes. It is essential for manufacturers in the cosmetics, chemical synthesis, and polymer industries seeking a reliable source for high-purity raw materials.

Application

• Hair Care & Cosmetics: Primary raw material for the production of thioglycolate salts used in hair waving (permanent waving) and depilatory (hair removal) creams.
• Chemical Synthesis: Key intermediate in the manufacture of pharmaceuticals, agrochemicals, and other specialty chemicals, often used to introduce thiol groups.
• Polymer Industry: Acts as a chain transfer agent (CTA) and modifier in the production of polyvinyl chloride (PVC) and acrylic resins to control molecular weight and improve properties.
• Oil & Gas: Used as a corrosion inhibitor and a component in formulations for metal cleaning and pickling in industrial processes.
• Analytical Chemistry: Serves as a chelating agent and a derivatization reagent for the analysis of metals and other compounds.
• Leather Processing: Employed in the tanning industry as a reducing agent.

Quality Control

Our Thioglycolic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets exacting standards for purity and consistency. Certificates of Analysis (COA) are provided with every shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizers and bases. Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Recommended storage temperature is 15-25°C.
