The actinic blueprint for maleic anhydride is C4H2O3, and its atomic weight is 98.06 g/mol.

Maleic anhydride is a achromatic to white solid that forms orthorhombic crystals and decomposes in water.

Maleic anhydride has an acid odor, with an odor beginning of 0.32 locations per actor (ppm).

The breath burden for maleic anhydride is 0.1 to 0.2 mm Hg at 25 °C.

Maleic anhydride is acclimated primarily in the accumulation of unsaturated polyester resins for use in boats, autos, trucks, buildings, piping, and electrical goods. Lube oil adhesives actinic from maleic anhydride are acclimated to prolong oil-change intervals and advance engine efficiency.

Maleic anhydride is aswell acclimated to accomplish copolymers, pesticides, and added amoebic compounds, and in Diels-Alder syntheses.
