Description

Thioglycollicacid80%Extrapure is a high-purity, concentrated aqueous solution of thioglycolic acid (TGA), a versatile organosulfur compound. This product is essential for applications requiring a potent reducing agent and a source of thiol groups with minimal impurity interference. It is a critical raw material for manufacturers in the cosmetics, chemical synthesis, and polymer industries, where consistent quality and reliable performance are paramount.

Application

• Cosmetics & Personal Care: Primary precursor for the synthesis of thioglycolate salts (e.g., ammonium thioglycolate, calcium thioglycolate) used in professional hair straightening (relaxing) and depilatory creams.
• Chemical Synthesis & Pharmaceuticals: Acts as a key intermediate and reducing agent in organic synthesis, including the production of certain pharmaceuticals and agrochemicals.
• Polymer Industry: Utilized as a chain transfer agent (CTA) in radical polymerization processes to control molecular weight and as a component in the synthesis of specialty polymers and resins.
• Analytical Chemistry & Research: Serves as a reagent for the determination of iron and other metals, and as a stabilizer or reducing agent in various laboratory procedures.
• Electroplating & Metal Treatment: Used in specific electroplating baths and as an additive for metal surface treatment and cleaning solutions.

Quality Control

Our Thioglycollicacid80%Extrapure is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, concentration, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and specific tests is provided with each shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its properties as a strong acid/organic solvent that is easily oxidized (store under inert atmosphere) and highly volatile, it should be kept separate from oxidizing agents, strong bases, and metals. Recommended storage temperature: 15-25°C.
