Description

Bis(2-Mercaptoethyl) Sebacate is a specialized organic compound featuring a long-chain sebacate core esterified with two terminal thiol (mercapto) groups. This unique molecular structure makes it a valuable multi-functional monomer and crosslinking agent in advanced polymer synthesis. It is primarily sought after by R&D and production teams in the polymer, adhesive, and specialty materials industries for its ability to introduce thiol functionality, enabling thiol-ene click chemistry, chain extension, and the formation of disulfide bonds for dynamic or self-healing materials.

Application

• Polymer Modification & Synthesis: Key monomer for producing polyurethanes, polyesters, and other polymers with built-in thiol functionality for further crosslinking or modification.
• Thiol-Ene "Click" Chemistry: Acts as a versatile dithiol component in photo-initiated or thermally initiated thiol-ene reactions for creating highly crosslinked networks in coatings, adhesives, and dental materials.
• Crosslinking Agent for Epoxy Resins: Used as a curing agent or co-curing agent for epoxy systems, imparting flexibility and improved chemical resistance to the final thermoset.
• Dynamic Covalent Chemistry: Serves as a precursor for introducing reversible disulfide linkages into polymer backbones, enabling the development of self-healing, recyclable, or stimuli-responsive materials.
• Adhesive & Sealant Formulations: Incorporated to enhance adhesion, flexibility, and cure properties in high-performance sealants and structural adhesives.
• Optical Material Production: Utilized in the synthesis of polymers with high refractive indices for optical lenses and components.

Quality Control

Our Bis(2-Mercaptoethyl) Sebacate is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Key parameters such as assay, thiol content, and impurity profiles are monitored. Certificates of Analysis (COA) detailing all specifications and test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Due to its thiol groups, this material is easily oxidized (store under inert atmosphere). Keep away from strong oxidizing agents, strong acids, and strong bases.
