Acrylic acid is an unsaturated carboxylic acid with the formula CH2=CHCOOH, widely used in the production of polyacrylates, superabsorbent polymers, and coatings. It serves as a key monomer in plastics, adhesives, and water treatment chemicals due to its reactive double bond. This clear, colorless liquid has a sharp odor and is highly versatile in industrial applications. CAS 79-10-7, molecular weight 72.06 g/mol, stored at ambient conditions. Hazard classification includes a signal word of *Danger* due to its corrosive and flammable properties. Molekula supplies acrylic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
