Chemische Eigenschaften
White to almost white crystalline powder. Insoluble in water, slightly soluble in hot water, easily soluble in benzene, acetone, ether, glacial acetic acid and other organic solvents.
Verwenden
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.
Definition
ChEBI: Cinnamic acid is a monocarboxylic acid that consists of acrylic acid bearing a phenyl substituent at the 3-position. It is found in Cinnamomum cassia. It has a role as a plant metabolite. It is a member of styrenes and a member of cinnamic acids. It is a conjugate acid of a cinnamate.
Allgemeine Beschreibung
trans-Cinnamic acid is an α,β-unsaturated aromatic acid that can be used as a flavoring agent. It is mainly used to prepare ester derivatives that are used in perfume industry.
trans-Cinnamic acid is the key volatile components of cinnamon essential oil.
l?uterung methode
Crystallise the acid from *benzene, CCl4, hot water, water/EtOH (3:1), or 20% aqueous EtOH. Dry it at 60o in vacuo. It is steam volatile. [Beilstein 9 IV 2002.]
