It belongs to the class of organic compounds known as coumaric acids and derivatives. It is also classified as a hydroxycoumaric acid. Coumaric acids are aromatic compounds containing a cinnamic acid moiety (or a derivative thereof) hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. There are two isomers of paprazine, N-trans-paprazine and N-cis-paprazine. Paprazine is a neutral, hydrophobic molecule that is largely insoluble in water.N-(p-Hydroxyphenyl)ethyl p-hydroxycinnamideN-p-trans-CoumaroyltyraminePaprazineC17H17NO3283.3218283.120843415(Z,2E)-3-(4-hydroxyphenyl)-N-[2-(4-hydroxyphenyl)ethyl]prop-2-enimidic acid(Z,2E)-3-(4-hydroxyphenyl)-N-[2-(4-hydroxyphenyl)ethyl]prop-2-enimidic acid36417-86-4OC1=CC=C(CCNC(=O)\C=C\C2=CC=C(O)C=C2)C=C1InChI=1S/C17H17NO3/c19-15-6-1-13(2-7-15)5-10-17(21)18-12-11-14-3-8-16(20)9-4-14/h1-10,19-20H,11-12H2,(H,18,21)/b10-5+RXGUTQNKCXHALN-BJMVGYQFSA-N belongs to the class of organic compounds known as coumaric acids and derivatives.
