Citraconic anhydride

Description:

Citraconic anhydride, with the CAS number 616-02-4, is a cyclic anhydride derived from citraconic acid. It is characterized by its colorless to pale yellow appearance and has a distinctive, slightly sweet odor. This compound is known for its reactivity, particularly as a dienophile in Diels-Alder reactions, making it valuable in organic synthesis. Citraconic anhydride is soluble in organic solvents such as acetone and ethanol but has limited solubility in water. Its chemical structure features a five-membered ring containing two carbonyl groups, which contributes to its electrophilic nature. This compound is utilized in the production of various polymers and as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Additionally, it can undergo hydrolysis to form citraconic acid in the presence of water. Safety precautions should be observed when handling citraconic anhydride, as it can be irritating to the skin and respiratory system. Overall, its unique properties make it a significant compound in both industrial and research applications.
