Description

2-Hydroxyethyl Methanethiosulfonate is a specialized organosulfur compound with a reactive thiosulfonate ester group. This chemical is valued for its role as a versatile intermediate and functionalizing agent in advanced organic synthesis and materials science. It is particularly relevant for researchers and manufacturers in the pharmaceutical, agrochemical, and polymer industries seeking to introduce sulfur-containing moieties or create cross-linked networks.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring thiol-protecting groups or controlled-release mechanisms.
• Bioconjugation & Protein Modification: Serves as a key reagent for site-specific modification of cysteine residues in proteins and peptides for drug delivery systems and diagnostic assays.
• Polymer Chemistry & Cross-linking Agent: Employed in the production of specialty polymers, hydrogels, and coatings to introduce disulfide linkages, enabling responsive or degradable material properties.
• Agrochemical Synthesis: Acts as a building block for developing novel fungicides, herbicides, and plant growth regulators that leverage sulfur chemistry.
• Chemical Research & Development: A valuable tool for organic chemists exploring new thiol-ene click chemistry reactions, sulfenylation processes, and the creation of functionalized surfaces.
• Material Science: Utilized in the functionalization of nanoparticles and surfaces to alter adhesion, biocompatibility, or catalytic properties.

Quality Control

Our 2-Hydroxyethyl Methanethiosulfonate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in opaque secondary packaging.
