2-Butenedioic acid (2E)-

Description:
2-Butenedioic acid, commonly known as fumaric acid, is an organic compound with the molecular formula C4H4O4. It is a dicarboxylic acid characterized by the presence of two carboxylic acid groups (-COOH) attached to a four-carbon chain, with a double bond between the second and third carbon atoms. This compound exists in two geometric isomers: the trans (E) form, which is the more stable and prevalent isomer, and the cis (Z) form. Fumaric acid is a white crystalline solid that is soluble in water and has a slightly acidic taste. It is used in various applications, including food additives, pharmaceuticals, and as a precursor in the synthesis of other chemicals. Additionally, fumaric acid plays a role in the human metabolism, particularly in the citric acid cycle. Its derivatives are also studied for potential therapeutic effects in treating certain medical conditions, such as psoriasis. Overall, fumaric acid is an important compound in both industrial and biological contexts.
