Maleic Anhydride

Maleic Anhydride (C4H2O3) is a water-reactive chemical taking the form of colorless crystalline needles, flakes, pellets, rods, briquettes, lumps or a fused mass. It is corrosive and will explode if confined. Because it is flammable, we recommend a safe chemical storage building that meets specific regulations for storing Maleic Anhydride.
