Description

2-Mercaptoethoxy Ethanol is a versatile organosulfur compound featuring both a thiol and a hydroxyl functional group, making it a valuable bifunctional intermediate. This unique structure provides exceptional reactivity for synthesizing specialized polymers, ligands, and surface modifiers. It is particularly sought after by manufacturers in the polymer, pharmaceutical, and specialty chemical industries for applications requiring precise molecular design and controlled functionalization.

Application

• Polymer Modification & Crosslinking Agent: Used to introduce thiol groups into polymer backbones for vulcanization, improving elasticity and thermal stability in rubbers and elastomers.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring thioether linkages.
• Metal Chelating Agent & Ligand Synthesis: Utilized to create chelating ligands for metal catalysis and extraction processes in hydrometallurgy.
• Surface Functionalization: Applied to modify the surface properties of materials like gold nanoparticles or silica for enhanced biocompatibility or specific binding.
• Adhesive & Sealant Formulations: Acts as a chain transfer agent or adhesion promoter in high-performance acrylic and epoxy-based systems.
• Chemical Synthesis Intermediate: A crucial precursor for synthesizing more complex molecules like thioethers, sulfones, and heterocyclic compounds in fine chemical production.

Quality Control

Our 2-Mercaptoethoxy Ethanol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC, to ensure high purity and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, documenting key parameters such as identity, purity, and impurity profiles to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. For long-term stability, storage under an inert atmosphere (e.g., nitrogen) is recommended to minimize oxidation of the thiol group. Recommended storage temperature: 2-8°C.
