Safety Profile
Moderately toxic by ingestion.When heated to decomposition it emits toxic vapors ofNOx.
Purification Methods
Wash the acid with distilled H2O and recrystallise it from aqueous AcOH, dry it and recrystallise again from EtOAc. Also recrystallise it from water or EtOH. UV: max 221, 252 and 305nm (EtOH). The amide crystallises from aqueous EtOH and has m 186-187o and max 218, 252 and 301nm.
