Applications

trans-Cinnamic acid is used in flavors, synthetic indigo and pharmaceuticals. It is involved in the production of methyl, ethyl and benzyl esters, which is used in the perfume industry. It serves as a precursor to the sweetener aspartame through enzyme-catalyzed amination to phenylalanine. It is a self-inhibitor produced by fungal spores to prevent germination. In addition, it is used to establish phenolic compounds by liquid chromatography, ultraviolet and mass spectrometry. It is utilized as a potential agent, thereby preventing lung tumor cells from metastasizing. Further, it induces intracellular release of calcium ions from the vacuole to the cytoplasm in order to trigger phytotoxicity in cucumber.

Notes

Incompatible with strong oxidizing agents.
