Light yellow to beige crystalline powder with aroma, soluble in methanol, ethanol, DMSO and other organic solvents, derived from synthesis.
4-Hydroxycinnamic acid is the hydroxy derivative of Cinnamic Acid with antioxidant properties. It is a is a major component of lignocellulose. Studies suggest that 4-Hydroxycinnamic acid may reduce the risk of cancer by reducing the formation of carcinogenic nitrosamines. A recent study reports that 4-Hydroxycinnamic acid may act as a chemical castrator in bees by altering the epression of genes required for ovary development. This compound is common in pollen a major constituent of the worker bee diet, but it is not found in queen bees'royal jelly.
p-Hydroxycinnamic acid is mainly used as an intermediate in the pharmaceutical and perfume industries. It can react with dimethyl sulfate to produce p-anisaldehyde, react with acetaldehyde to produce p-hydroxycinnamaldehyde, and further oxidize it to produce cinnamic acid. This product can be directly oxidized to produce 4-Hydroxybenzoic acid and reduction to produce 4-Hydroxybenzyl alcohol.
ChEBI: 4-coumaric acid is a coumaric acid in which the hydroxy substituent is located at C-4 of the phenyl ring. It has a role as a plant metabolite. It is a conjugate acid of a 4-coumarate.
