Description

2-Mercaptoethyl Decanoate is a specialized organosulfur compound that serves as a versatile intermediate and functional additive in advanced chemical synthesis. Its molecular structure, featuring both a thiol and an ester group, makes it a valuable building block for introducing specific functionalities into polymers, lubricants, and other performance materials. This product is primarily utilized by R&D chemists and process engineers in the polymer, lubricant additive, and specialty chemical industries seeking to modify material properties or create novel compounds.

Application

• Polymer Modification: Acts as a chain transfer agent (CTA) or cross-linking agent in radical polymerization processes to control molecular weight and introduce thiol end-groups.
• Lubricant & Fuel Additive: Functions as an extreme pressure (EP) additive and anti-wear agent in synthetic lubricants and industrial oils.
• Chemical Intermediate: Serves as a key synthon for the production of more complex sulfur-containing compounds in pharmaceutical and agrochemical research.
• Surface Functionalization: Used to create self-assembled monolayers (SAMs) on metal surfaces for corrosion inhibition or to alter surface energy.
• Adhesive & Sealant Formulation: Imparts improved adhesion and flexibility as a reactive modifier in epoxy and polyurethane systems.
• Rubber Vulcanization: Employed as a secondary accelerator or vulcanizing agent in the production of specialty elastomers.

Quality Control

Our 2-Mercaptoethyl Decanoate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to ensure consistent purity and meet defined specifications. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality system is designed to support applications requiring reliable and traceable material performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents, strong bases, and sources of heat.
