  • Applications

    Monomethyl Fumarate (CAS 2756-87-8) is primarily used as an organic synthesis intermediate, supporting the production of pharmaceutical and agrochemical compounds; it can act as a reactive monomer or building block for specialty polymers and coating/adhesive formulations by enabling radical polymerization of unsaturated ester functionalities; it serves as a precursor for various fumarate derivatives used in resin formulations and binder systems; it may be employed in UV-curable coating and adhesive platforms due to its ester and C=C functionalities; and it is evaluated as a versatile starting material for esterification/transesterification routes to create tailored fumarate derivatives for industrial use.
