Description

Thioglycolic Acid n-Butyl Ester is a versatile organosulfur compound widely used as a key intermediate and additive in industrial synthesis. Its value lies in its ability to act as a source of the thiol functional group and as a plasticizer or stabilizer in polymer systems. This ester is essential for manufacturers in the polymer, chemical synthesis, and specialty materials sectors seeking reliable, high-purity raw materials.

Application

• Polymer Additive: Used as a plasticizer and stabilizer in PVC and other polymer formulations to enhance flexibility and processing characteristics.
• Chemical Intermediate: Serves as a crucial building block in the synthesis of more complex sulfur-containing compounds for pharmaceuticals and agrochemicals.
• Crosslinking Agent: Employed in the production of specialty resins and elastomers where sulfur-based crosslinks are required.
• Lubricant Additive: Functions as an extreme pressure (EP) additive and anti-wear agent in advanced lubricant formulations.
• Analytical Reagent: Utilized in specific analytical chemistry applications for derivatization or as a reference standard.
• Adhesive Formulation: Acts as a component in certain specialty adhesive systems to modify cure profiles and final properties.

Quality Control

Our Thioglycolic Acid n-Butyl Ester is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as assay, appearance, and impurity profiles to guarantee consistency and reliability for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), it is recommended to store under an inert gas (e.g., nitrogen) for long-term stability. Recommended storage temperature is 2-25°C.
