Description
Sodium Allylsulfonate (CAS 2495-39-8, EC 219-676-5) is a water-soluble sulfonate monomer also known as Allyl Sodium Sulfonate and Sodium 2-Propene-1-Sulfonate. It carries no assigned E-code. The compound belongs to the monomers and building blocks category and is supplied as a white powder.
In polymer manufacturing, Sodium Allylsulfonate is incorporated as a reactive comonomer to introduce permanent sulfonate groups into polymer backbones, improving hydrophilicity and antistatic performance in synthetic fibres and coatings. In water treatment and leather processing, its antimicrobial activity supports preservation at the formulation stage, reducing microbial load during processing.
Sodium Allylsulfonate is available in technical grade as a dry powder and falls under HS code 29041000 for customs classification. It is subject to REACH registration requirements within the European Economic Area. Buyers should confirm lot-specific purity documentation and packaging format directly with the supplier.
