2,3-Dimethylmaleic anhydride Chemical Properties,Usage,Production

Chemical Properties

white to beige crystals or cryst. powder

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.

Definition

ChEBI: 2,3-Dimethylmaleic anhydride is a butenolide. It is a 5-membered cyclic anhydride with a double bond between carbon atoms C2 and C3. The double bond locks the molecule in a planar conformation and stabilizes the acid anhydride against hydration. It was used as linker to a cell penetrating peptidebased nanoparticle.

Safety Profile

Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes. See also ANHYDRIDES.

Purification Methods

Distil the anhydride from *benzene/ligroin and sublime in a vacuum. [Beilstein 17/11 V 69.]
