我只听说过最高85%的水合肼，为什么在European Journal of Medicinal Chemistry 42 (2007) 146 151 上见到了Equimolar quantities
of N,N-phthaloyl GABA (0.03 mol) and hydrazine hydrate
(99-100%) (0.03 mol) were condensed in the presence of
DCC (0.03 mol) in dichloromethane, by stirring at ice-cold con-
ditions .
难道还有99%-100%这么高纯度的水合肼吗，或者是其他的什么意思？
