Fumaric acid (MF: C₄H₄O₄, MW: 116.07), also known as fumaric acid or trans-butenedioic acid, occurs naturally in Corydalis, mushrooms, and fresh beef. It serves as a vital organic chemical feedstock, an intermediate in fine chemical products, and a key derivative of maleic anhydride. Its highly reactive chemical properties enable participation in Diels-Alder reactions; polymerisation, addition reactions, and other chemical processes. It finds extensive application in foodstuffs, coatings, resins, and plasticisers.
