Description

Hexanedioic Acid 1-(2-Mercaptoethyl)6-Methyl Ester is a specialized organosulfur compound that serves as a versatile intermediate and functional additive. Its molecular structure, featuring both an ester linkage and a thiol (mercapto) group, makes it valuable for introducing sulfur-based functionality into polymers and fine chemicals. This compound is primarily sought by R&D and production teams in the polymer, pharmaceutical, and specialty chemical industries for applications requiring cross-linking, chain transfer, or specific molecular modifications.

Application

• Polymer Modification & Cross-linking Agent: Used in the synthesis and modification of polymers, including polyurethanes and acrylics, to introduce thiol groups for subsequent cross-linking or to alter material properties.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules that require a thioether or disulfide linkage.
• Adhesive & Sealant Formulations: Acts as a reactive diluent or adhesion promoter in high-performance adhesive and sealant systems, enhancing flexibility and chemical resistance.
• Lubricant & Fuel Additive Precursor: Utilized in the production of extreme pressure (EP) additives and anti-wear agents for lubricants and industrial fluids.
• Chemical Synthesis Reagent: Employed in organic synthesis as a thiol-containing reagent for Michael additions, thiol-ene click chemistry, and other coupling reactions.
• Surface Coating Agent: Incorporated into coatings to improve surface characteristics, such as corrosion resistance and substrate adhesion.

Quality Control

Our Hexanedioic Acid 1-(2-Mercaptoethyl)6-Methyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and functional group verification, to ensure it meets precise customer specifications and industry standards. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its properties of being light-sensitive and easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents and heat sources.
