Definition
ChEBI: 3-(4-phenyl-1-piperazinyl)propane-1,2-diol is a member of piperazines.
Manufacturing Process
34 g 1,2-epoxy-3-hydroxypropane (glycide) in 50 ml of water were added to 64.8 g 1-phenylpiperazine in 80 ml of ethanol at the temperature not higher 50°C. The mixture was stood at night, then it was evaporated to dryness in vacuum and the stark product was recrystallized from 100 ml of acetone to give 60 g 1-phenyl-4-(2,3-dihydroxypropyl)piperazine (dropropizine) MP 105°C; BP 205°C/1 mm Hg.
Therapeutic Function
Antitussive
