trans-2,4-Pentadienoic acid

Description:

Trans-2,4-Pentadienoic acid, also known as trans-2,4-hexadienoic acid, is an unsaturated fatty acid characterized by its two double bonds located at the second and fourth carbon positions of the carbon chain. This compound has a molecular formula of C5H6O2 and features a trans configuration, which influences its physical and chemical properties. It is typically a colorless to pale yellow liquid with a pungent odor. The presence of double bonds contributes to its reactivity, making it susceptible to oxidation and polymerization. Trans-2,4-Pentadienoic acid is soluble in organic solvents but has limited solubility in water due to its hydrophobic nature. It is used in various chemical syntheses and may serve as an intermediate in the production of other compounds. Additionally, its structural characteristics make it of interest in studies related to fatty acid metabolism and the development of bioactive molecules. Safety precautions should be taken when handling this compound, as it may cause irritation to the skin and eyes.
