Cyclohexenylmethyl Methacrylate (CAS 21367-03-3) has a molecular formula of C??H??O? and molecular weight of 194.27 g/mol, consisting of a cyclohexenylmethyl group and a methacrylate moiety (-O?C-C(CH?)=CH?). As a functional monomer, it is widely used in polymer synthesis (e.g., coatings, adhesives) to enhance polymer flexibility and chemical resistance. It should be stored sealed with a polymerization inhibitor under cool conditions to prevent unwanted polymerization, ensuring reactivity for industrial applications.
