2-(4-Aminophenyl)ethylamine

clear light yellow to brown-yellow viscous liquid

4-(2-Aminoethyl)aniline has been used in chemical modification of silk fibroin to tailor the overall hydrophilicity and structure of silk. It has been used as reagent in polycondensation reactions.

2-(4-Aminophenyl)ethylamine (APEA) is an important amine compound for the study of reductive amination with 3-deoxy-d-mannuronic acid (Kdo) and for the synthesis of new heat-resistant biopolyureas by fermentation techniques^[1-2].
