Product Name:Itaconic Anhydride
English Name:Itaconic Anhydride
CAS No.:2170-03-8
Aliases:Methylenesuccinic Anhydride, 2-Methylene-3-oxocyclopentane-1-carboxylic anhydride
Molecular Formula:C5H4O3
Physical Properties:Off-white to pale yellow crystalline solid. Melting point 66-68°C, boiling point 114-115°C (12 mmHg), relative density approximately 1.3 g/cm³. Readily soluble in ethanol, ether, acetone and other organic solvents; slowly decomposes in water to itaconic acid. Stable in air, hygroscopic.
Uses:Primarily used as an organic synthesis intermediate for the preparation of itaconate plasticizers, copolymer monomers, and fine chemicals. It serves as a crosslinking monomer in coatings, adhesives, and resin modification, significantly improving the heat resistance and mechanical strength of polymers. It is also used in the synthesis of agrochemical and pharmaceutical intermediates.
