Description

3-Chloro-2-Hydroxypropanesulphonic Acid is a versatile organosulfur compound with a reactive chlorohydrin and sulfonic acid group. This unique bifunctional structure makes it a valuable intermediate for introducing sulfonate functionality into target molecules. It is primarily sought after by manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for synthesizing surfactants, scale inhibitors, and biologically active compounds.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring sulfonate groups for enhanced solubility or biological activity.
• Surfactant & Detergent Synthesis: Used in the production of anionic surfactants and detergent additives, imparting excellent wetting, foaming, and emulsifying properties.
• Agrochemical Formulations: Serves as an intermediate for herbicides, fungicides, and plant growth regulators, improving formulation stability and efficacy.
• Water Treatment Chemicals: Acts as a precursor for scale and corrosion inhibitors used in industrial cooling and boiler water systems.
• Textile & Leather Auxiliaries: Employed in the synthesis of leveling agents, dyeing assistants, and tanning agents for the textile and leather industries.
• Polymer Modification: Used to introduce hydrophilic sulfonate groups into polymers, enhancing their compatibility, antistatic properties, or dyeability.
• Research & Development: A valuable reagent in organic synthesis for academic and industrial R&D laboratories exploring new chemical entities.
