Description

2-Ethylhexyl Mercaptoacetate is a specialized organosulfur compound widely used as a key intermediate and additive in polymer and materials science. Its primary value lies in its ability to act as a chain transfer agent or a source of thiol functionality, enabling precise control over polymer molecular weight and introducing specific reactive sites. This chemical is essential for manufacturers in the polymer, coatings, and specialty chemical industries seeking to modify material properties such as flexibility, adhesion, and cross-linking density.

Application

• As a chain transfer agent (CTA) in the production of acrylic and styrenic polymers to regulate molecular weight and polydispersity.
• As a key intermediate in the synthesis of PVC stabilizers and other polymer additives.
• As a cross-linking agent or modifier in the formulation of specialty adhesives, sealants, and coatings.
• In the production of lubricant additives and fuel additives where sulfur-containing compounds are required.
• As a chemical building block for synthesizing more complex thioesters and sulfur-based specialty chemicals.
• In research and development for creating novel functional materials with tailored surface properties.

Quality Control

Our 2-Ethylhexyl Mercaptoacetate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every 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 sources and incompatible materials. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Recommended storage temperature is 15-25°C.
