Itaconic acid, also known as 2,3-epoxypropyl monoester, is a white crystalline organic compound with the chemical formula C5H6O4. It is a derivative of acrylic acid and is produced through the fermentation of carbohydrates by certain bacteria, such as Aspergillus terreus. Itaconic acid has a wide range of applications, including the production of unsaturated polyester resins, adhesives, and coatings. It is also used as a chelating agent, a pH regulator, and a precursor for the synthesis of other chemicals. Due to its versatility and biodegradability, itaconic acid is considered an environmentally friendly alternative to traditional petrochemical-based products.
