(E)-2-Methyl-2-pentenoic acid

Description:
(E)-2-Methyl-2-pentenoic acid, with the CAS number 16957-70-3, is an unsaturated carboxylic acid characterized by a double bond between the second and third carbon atoms in its pentene chain. This compound features a methyl group at the second carbon, contributing to its branched structure. It is a colorless to pale yellow liquid with a distinctive odor, typical of organic acids. The presence of the carboxylic acid functional group (-COOH) imparts acidic properties, allowing it to participate in various chemical reactions, such as esterification and polymerization. Its unsaturation makes it reactive, particularly in addition reactions. The compound is soluble in organic solvents and exhibits limited solubility in water due to its hydrophobic hydrocarbon chain. (E)-2-Methyl-2-pentenoic acid is of interest in organic synthesis and may serve as an intermediate in the production of various chemical products, including pharmaceuticals and agrochemicals. Safety data should be consulted for handling and storage, as it may pose health hazards.
