Description and Uses
2,3-Dimethylmaleic anhydride can be usually used in the synthesis of maleimides and as an amino group protecting agent for superoxide dismutase. It is also used in the preparation of dimethylmaleic acid dimethyl ester. Further, it serves as a reactant in the dissociation of ribosomal proteins. In addition to this, The isolated molecule 2, 3-dimethylmaleic anhydride showed potent insecticidal activity in fumigation bioassay against several insect species, viz., adults of houseflies, cockroaches and stored-product insects.
