Participants

Reaction Steps

L-arginine hydrofluoride phosphate was prepared by combining 34.8 gm. of L-arginine (free-base) with 8 gm. of a 50% aqueous solution of hydrofluoride and 23.5 gm. of orthophosphoric acid. This was dissolved in about 75 ml. of water. The resulting syrup was poured into about 750 ml. of a methanol-ethanol mixture to precipitate the salt. After filtration the cake (L-arginine hydrofluoride phosphate) was rinsed with methanol and air dried.
