Application

Methylhydrazine can be used to induce asymmetric aerobic epoxidation of β-trifluoromethyl-β,β-disubstituted enones to synthesize enantioselective trifluoromethyl-substituted epoxides. It can also be used to synthesize 1-methyl-3,5-dinitro-1H-1,2,4-triazole (DNMT), a substitute for TNT explosive.

Capillary electrophoresis (CE)/electrochemical detection (EC) for the simultaneous detection of hydrazine, methylhydrazine, and isoniazid has been developed with a 4-pyridyl hydroquinone self-assembled microdisk platinum electrode. Such an electrode has very high catalytic ability for hydrazines and they could be detected
