Acrylic acid sodium salt is a water-soluble salt used in polymer synthesis and water treatment, serving as a monomer for polyacrylates and superabsorbent polymers. It is a key intermediate in the production of superabsorbent polymers and coatings. Available in powder form, it has a molecular formula of C3H3NaO2, a molecular weight of 94.04 g/mol, and is stable at ambient temperatures. It carries a Warning signal word due to its aquatic toxicity, being very toxic to aquatic life (H400) and toxic to aquatic life with long-lasting effects (H411). Molekula supplies Acrylic acid sodium salt from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
