Overview

3-(Diethylamino)propylamine (3-(diethylamino)-1-propylamine, DEAPA) is a diamine.
3-(Diethylamino)propylamine may be used in the preparation of: Biocompatible polyampholyte-coated (poly(acrylic acid)-co-3-(diethylamino)-propylamine magnetite nanoparticles (PAMNPs). Hyaluronic acid grafted with 3-diethylaminopropyl (DEAP) group (HA-g-DEAP) nanoparticles for use as a drug delivery vehicle. DEAPA-modified poly(vinyl alcohol) (PVA) polymers that can be employed in gene silencing. It may also be used to introduce cationic groups during the surface modification of microfibrillated cellulose (MFC).
