Sodium allylsulfonate（Cat No.:L045251）is an organosulfur compound with the formula C₃H₅SO₃Na. It appears as a white crystalline powder or granule, readily soluble in water. The molecule contains an allyl group (–CH₂CH=CH₂) bonded to a sulfonate group, giving it both reactivity and ionic character. Sodium allylsulfonate is widely used as a monomer or comonomer in the production of sulfonated polymers, ion-exchange resins, and water treatment agents. It also serves as an additive in electroplating baths, dispersants, and superplasticizers, offering improved conductivity, dispersibility, and surface activity in various industrial formulations.
