Product Description:

Trans-p-Hydroxycinnamic acid, also known as p-coumaric acid, is a hydroxy derivative of cinnamic acid. It is a naturally occurring phenolic compound widely found in plants, including peanuts, tomatoes, carrots, and garlic. It exists as a white to light yellow crystalline powder. Its primary significance lies in its role as a key intermediate in the biosynthesis of other important plant metabolites, such as flavonoids, lignin, and other phenylpropanoids. Due to its antioxidant, anti-inflammatory, and antimicrobial properties, it is extensively studied in the fields of nutraceuticals, cosmetics, and pharmaceuticals. It serves as a precursor for the synthesis of various bioactive compounds and is also used as a standard in analytical chemistry for the quantification of phenolic acids. As a simple cinnamic acid derivative containing both a carboxylic acid and a phenolic hydroxyl group, it is a versatile building block in organic synthesis for constructing more complex molecular architectures, particularly in medicinal and materials chemistry.
