trans2butenoic

trans2butenoic acid, also known as crotonic acid, is an unsaturated carboxylic acid with the chemical formula C4H6O2. It is a structural isomer of 2-butenoic acid that exists in the trans configuration, meaning the two hydrogen atoms attached to the double bond are on opposite sides. It is a colorless crystalline solid with a pungent odor. Trans2butenoic acid is soluble in water and organic solvents. It is a weak acid.

This compound is found naturally in some plants and can be produced industrially through various chemical processes. One common method involves the oxidation of crotonaldehyde. Trans2butenoic acid is used as a monomer in the production of polymers and resins. It also finds applications as an intermediate in the synthesis of pharmaceuticals, fragrances, and other organic chemicals. Its reactivity stems from both the carboxylic acid group and the carbon-carbon double bond, allowing for a range of chemical transformations. The distinct trans stereochemistry is crucial for its specific chemical properties and reactions.
