Description

Sodium 3-Chloro-2-Hydroxypropanesulphonate Hemihydrate is a versatile organosulfonate intermediate with a reactive chlorohydrin functional group. This compound is valued for its ability to introduce sulfonate and reactive sites into molecules, enhancing water solubility and providing points for further chemical modification. It is primarily sought by manufacturers in the detergent, textile, and specialty chemical synthesis industries for producing surfactants, dye intermediates, and functional monomers.

Application

• Surfactant and Detergent Intermediate: Key building block for synthesizing anionic surfactants and hydrotropes used in liquid detergents, cleaning formulations, and personal care products.
• Textile Chemical Synthesis: Used in the production of leveling agents, dyeing auxiliaries, and anti-static agents for the textile processing industry.
• Polymer Modification: Serves as a monomer or co-monomer for introducing sulfonate groups into polymers to improve hydrophilicity, dyeability, and antistatic properties.
• Pharmaceutical Intermediate: Employed in the synthesis of certain active pharmaceutical ingredients (APIs) and prodrugs requiring sulfonate functionality.
• Paper and Pulp Chemicals: Component in the synthesis of dispersants and process aids used in paper manufacturing.
• Water Treatment Formulations: Intermediate for scale inhibitors and dispersants in industrial water treatment systems.
• Electroplating Additive: Used in the preparation of brighteners and auxiliary agents for electroplating baths.
• Research & Development: Valuable reagent in organic synthesis and chemical research for constructing complex sulfonated molecules.

Quality Control

Our Sodium 3-Chloro-2-Hydroxypropanesulphonate Hemihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) detailing assay, impurity profile, and physical parameters are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
