Common Name

Epinine

Description

Epinine, also known as deoxyepinephrine or deoxyadrenaline, is a member of the class of compounds known as catecholamines and derivatives. These compounds contain 4-(2-aminoethyl)pyrocatechol [4-(2-aminoethyl)benzene-1,2-diol] or a derivative thereof formed by substitution. Epinine exists as a solid, and is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Epinine is an alkaloid from Vicia faba and can be found in pulses. Epinine is a dopamine and epinephrine derivative.
