Product Usage

The compound is a high-tonnage chemical and is widely used in a variety of industrial organic syntheses. Phthalic anhydride is used in the manufacture of unsaturated polyesters and as a curing agent for epoxy resins. When used as a pigment, it can be responsible for sensitization in ceramic workers. Phthalic Anhydride is an organic compound and the anhydride of phthalic acid (P384480). Phthalic Anhydride is an important industrial chemical commonly used in large-scale production of plasticizers f or plastics. Recent research have also evaluated Phthalic Anhydride as potential antibacterial agent.
manufacture of phthaleins, phthalates, benzoic acid, synthetic indigo, artificial resins (glyptal).
