3 Chloro 2 Hydroxy 1 Propanesulfonicacid Sodiumsalt (CHPS Na)

3-Chloro-2-Hydroxy-1-Propanesulfonic acid Sodium salt, frequently abbreviated as CHPS-Na or simply CHPS sodium, is a highly functionalized organosulfonate compound serving as a critical intermediate in contemporary chemical synthesis. This white crystalline powder or aqueous solution exhibits exceptional solubility in water due to its ionic nature and polar functional groups. Characterized by the presence of a reactive chlorine atom, a secondary hydroxyl group, and a sulfonic acid sodium salt moiety, it acts as a versatile building block for introducing hydrophilic sulfonic acid groups into various substrates. In industrial chemistry, it is primarily valued for its role as a sulfonating agent, enabling the modification of polymers and surfactants to enhance their solubility and performance. Its unique molecular architecture allows for precise nucleophilic substitution reactions, making it indispensable in the production of specialized water treatment chemicals, personal care additives, and oilfield surfactants. Its stability under varying pH conditions further underscores its utility in manufacturing.
