(2E,4Z)-2,4-Hexadienoic acid, also known as sorbic acid, is an unsaturated fatty acid characterized by its two double bonds located at the second and fourth carbon positions of the hexane chain. This compound features a trans configuration at the second double bond and a cis configuration at the fourth, which influences its chemical reactivity and physical properties. It is a colorless to pale yellow liquid with a characteristic odor and is soluble in organic solvents but has limited solubility in water. The presence of double bonds contributes to its reactivity, making it susceptible to oxidation and polymerization. (2E,4Z)-2,4-Hexadienoic acid is widely used as a food preservative due to its antimicrobial properties, inhibiting the growth of molds and yeasts. Additionally, it serves as an intermediate in the synthesis of various chemical compounds in the food and cosmetic industries. Its safety profile is generally favorable, but it should be handled with care due to potential irritant effects.

Sorbic acid is a natural organic compound that is found in many plants, such as apples and apricots. It is also used as an anti-fungal agent in food preservation. Sorbic acid has the chemical formula CH2=CHCOOH. The two geometric isomers of sorbic acid are cis-sorbic acid (or meso-sorbic acid) and trans-sorbic acid. Trans-sorbic acid has a melting point of 98°C, while cis-sorbic acid melts at 112°C.

Applications trans,cis-Sorbic acid has been used in the study of photosensitization of carbon nanotubes and the production of reactive oxygen species by using the sorbic acid as a catalyst in the reaction process.
