Description

Sodium 4-Chloro-1-Hydroxybutanesulfonate is a versatile organosulfonate intermediate with a reactive chlorohydroxy functional group. This compound is valued for its bifunctional reactivity, enabling its use as a key building block in the synthesis of surfactants, pharmaceuticals, and specialty polymers. It is primarily sought by manufacturers in the fine chemical, detergent, and pharmaceutical intermediate sectors for its ability to introduce sulfonate and reactive halogen functionalities into target molecules.

Application

• Surfactant Intermediate: A key precursor for the synthesis of anionic surfactants and hydrotropes used in industrial and household cleaning formulations.
• Pharmaceutical Synthesis: Serves as a versatile building block in the production of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring sulfonate or chlorinated side chains.
• Polymer Modification: Used to introduce hydrophilic sulfonate groups into polymers, enhancing their water solubility, dyeability, or antistatic properties.
• Chemical Intermediate: Employed in organic synthesis for the preparation of more complex sulfonated or halogenated compounds in research and development.
• Electroplating Additives: Can function as a brightener or leveling agent component in electroplating baths.
• Textile Auxiliaries: Utilized in the production of dyeing assistants and finishing agents for textiles.
