Description

Sodium 2-Chloroethanesulfonate Monohydrate is an important organosulfur compound and a versatile chemical intermediate. This product is valued for its ability to introduce sulfonate and reactive chloroethyl functional groups into target molecules, enabling the synthesis of surfactants, pharmaceuticals, and specialty polymers. It is primarily sought by research and development laboratories, pharmaceutical manufacturers, and chemical producers in the fine chemical and agrochemical sectors.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfonate or taurine-related moieties.
• Surfactant & Detergent Precursor: Used in the production of specialized anionic surfactants and detergent additives for enhanced performance.
• Polymer Modification: Serves as a monomer or functionalizing agent for creating water-soluble polymers and ion-exchange resins.
• Biochemical Research: Employed in proteomics and biochemistry as a reagent for protein modification or buffer component studies.
• Agrochemical Synthesis: Intermediate in the manufacture of certain herbicides and plant growth regulators.
• Electroplating Additive: Can be used in electroplating baths to improve surface finish and deposition quality.
