Mtengo wa Wopereka p-Coumaric acid yokhala ndi CAS 501-98-4
Trans-4-hydroxycinnamic acid ndi mtundu wa cinnamic acid compound, yomwe imafalikira kwambiri muzinthu zambiri zachilengedwe monga propolis, ndiwo zamasamba ndi zipatso, ndipo ndi antioxidant yachilengedwe. Makamaka mu mawonekedwe a organic acid esters, polyglycosides ndi amides amapezeka kwambiri m'chilengedwe. Khalidwe 4- hydroxycinnamic acid ndi ufa woyera kapena wachikasu wopepuka. Sungunuka mu hot ether, hot ethanol, sungunuka pang'ono mu benzene, osasungunuka mu petroleum ether.

4-hydroxy-coumarin ndi mankhwala oletsa magazi kuundana kwa magazi, rodenticide, bromadiron, bromurin, rodenticide, rodenticide, rodenticide, flurodenticide, tiamurin, cordenticide, ndi zina zotero.
Mankhwala oletsa magazi kuundana amatha kupangidwa m'mankhwala, monga double coumarin ethyl ester ndi ketone benzyl coumarin.
Amagwiritsidwa ntchito ngati gawo lapakati pamakampani opanga mankhwala ndi zonunkhira.
Trans-4-hydroxycinnamic acid ndi e-isomer ya p-coumaric acid, yomwe ndi hydroxyl derivative ya cinnamic acid ndipo ili ndi mphamvu zoteteza ku ma antioxidants. Coumaric acid ndi gawo lalikulu la lignocellulose. Kafukufuku wasonyeza kuti p-coumaric acid ingachepetse chiopsezo cha khansa pochepetsa kupangika kwa nitrosamines zomwe zimayambitsa khansa.
