off-white to yellow-beige crystalline

3-Chloropropylamine hydrochloride was used in chemical treatment of carbon-enriched fly ash concentrates.It was used in the synthesis of linear, star and comb-like polyacrylamides by atomic transfer radical polymerization. It was used in the synthesis of halogen-functionalized aliphatic polyketones (macroinitiators).

General procedure for the synthesis of 3-chloropropylamine hydrochloride from 3-amino-1-propanol: An anhydrous chloroform (30 mL) solution of thionyl chloride (8.68 g, 1.32 mmol) was slowly added dropwise to 3-amino-1-propanol (4.49 g, 59.19 mmol) at 0-10°C. The reaction mixture was heated to room temperature and refluxed for 3 hours. The reaction mixture was gradually warmed to room temperature and then heated to reflux for 3 hours. After completion of the reaction, the mixture was cooled to room temperature and the precipitate was collected by filtration to afford the target product 3-chloropropylamine hydrochloride (7.07 g, 55.15 mmol, 93% yield) as a green solid. Electrospray mass spectrometry (ESMS) showed m/z 94 ([M+H]+).
