Description

Sodium 2,3-Epoxypropane-1-Sulphonate is a versatile organosulfur compound and sodium salt, widely recognized as a key intermediate and functional additive in advanced chemical synthesis. Its reactive epoxide and sulfonate groups make it valuable for introducing hydrophilic, anionic, and cross-linking functionalities into polymer chains. This chemical is essential for manufacturers in the water treatment, textile, and personal care industries seeking to enhance product performance through tailored chemical modification.

Application

• Polymer & Resin Modification: Acts as a reactive monomer or cross-linking agent in the production of specialty polymers, ion-exchange resins, and epoxy-based materials.
• Water Treatment Chemicals: Used as a building block for synthesizing scale inhibitors, dispersants, and antiscalants in industrial water systems.
• Textile & Leather Auxiliaries: Serves as an intermediate for creating leveling agents, dye-fixing agents, and softening agents to improve fabric processing and quality.
• Personal Care & Detergents: Employed in the synthesis of mild surfactants and conditioning agents for shampoos, body washes, and high-performance cleaning formulations.
• Paper & Pulp Industry: Functions as a component in the manufacture of wet-strength resins and retention aids.
• Pharmaceutical Intermediates: Utilized as a key synthon in the production of certain active pharmaceutical ingredients (APIs) and diagnostic agents.

Quality Control

Our Sodium 2,3-Epoxypropane-1-Sulphonate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results for assay, moisture content, and related substances are provided to guarantee consistent quality and traceability for your critical applications.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and stability.
