Industrial Applications
Unsaturated Polyester Resins
Primary feedstock for unsaturated polyester resins (UPR) used in fiberglass composites, marine, construction, and automotive applications.
Alkyd Resins
Modifier in alkyd resin synthesis to improve hardness, drying speed, and chemical resistance in oil-based coatings.
Maleic Acid & Fumaric Acid
Hydrolysis produces maleic acid; isomerization produces fumaric acid — both used in food, pharmaceutical, and polymer applications.
Copolymers & Adhesives
Comonomer in styrene-maleic anhydride (SMA) and vinyl acetate-maleic anhydride copolymers for adhesives, coatings, and dispersants.
Agricultural Chemicals
Intermediate in synthesis of malathion insecticide and other organophosphate agrochemicals.
Lubricant Additives
Feedstock for succinic anhydride derivatives used as dispersants and detergents in engine oil additive packages.
Safety & Regulatory
Corrosive Solid — Respiratory Sensitizer
Maleic anhydride dust and vapors are corrosive to the respiratory tract and skin. Use respiratory protection and chemical-resistant gloves. SDS available upon request.

Maleic anhydride is a reactive cyclic anhydride used as a key intermediate in resins, coatings, and agricultural chemicals. Here's how it compares.
| Attribute | Maleic Anhydride | Phthalic Anhydride | Acetic Anhydride |
|---|---|---|---|
| Physical State | White crystalline solid (flakes/briquettes) | White flakes or powder | Colorless liquid |
| Reactivity | Highly reactive — dienophile, electrophile | Reactive — less than maleic | Reactive — acetylating agent |
| Primary Use | Unsaturated polyester resins, agricultural chemicals | Alkyd resins, plasticizers | Cellulose acetate, pharmaceuticals |
| Melting Point | 52.8 °C (127 °F) | 131 °C (268 °F) | −73 °C (liquid at room temp) |
| Hazard | Irritant — respiratory sensitizer | Irritant — respiratory sensitizer | Corrosive — flammable liquid |
