Participants

Reaction Steps

A glycerol solution of L-histidine hydrofluoride phosphate was prepared by suspending 15.5 gm. of free-base L-histidine in 168 gm. of glycerol. Then 4 gm. of a 50% aqueous solution of hydrofluoric acid and 11.5 gm. of orthophosphoric acid were added. The mixture slowly dissolved over night to yield a slightly cloudy solution. The resulting solution was diluted to about 200 gm. with glycerol.
