Description

Bis(2-Mercaptoethyl) Succinate is a specialized organic compound featuring a succinate core flanked by two mercaptoethyl groups, making it a valuable sulfur-containing building block. Its primary commercial value lies in its dual thiol functionality, which enables its use as a cross-linking agent, chain transfer agent, or intermediate in the synthesis of more complex molecules. This product is essential for manufacturers and R&D teams in the polymer, pharmaceutical, and specialty chemical industries seeking to introduce sulfur-based reactivity or modify material properties.

Application

• Polymer Modification & Cross-linking: Acts as a key monomer or cross-linker in the production of specialty polymers, including polyurethanes and polysulfides, to enhance properties like elasticity, chemical resistance, and thermal stability.
• Pharmaceutical Intermediate: Serves as a crucial synthetic building block for active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring thiol-ene chemistry or specific sulfur-containing motifs.
• Adhesive & Sealant Formulations: Utilized in high-performance adhesives and sealants where its mercaptan groups contribute to curing mechanisms and improve adhesion to various substrates.
• Lubricant & Fuel Additive Synthesis: Employed as an intermediate in creating extreme pressure (EP) additives and antioxidants for lubricants and industrial fuels.
• Chemical Research & Development: Used in academic and industrial R&D labs as a versatile reagent for organic synthesis, material science, and exploring new chemical pathways.
• Surface Modification Agent: Facilitates the functionalization of surfaces and nanoparticles through thiol-based coupling reactions for advanced material applications.

Quality Control

Our Bis(2-Mercaptoethyl) Succinate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with customer specifications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. For specific regulatory or grade requirements (e.g., research, technical, or custom purity), please contact our technical support team.

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 easily oxidized and highly volatile, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) when in partially used containers and to minimize exposure to air and moisture. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents.
