Methylhydrazines are hydrazines that have additional methyl groups. Heavily methylated versions exist as hydrazinium salts. Members of this class include:
Monomethylhydrazine Monomethylhydrazinium (cationic and exists as a variety of salts) Dimethylhydrazines Symmetrical dimethylhydrazine (1,2-dimethylhydrazine) Unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine) Trimethylhydrazine 1,1,2-trimethylhydrazine 1,1,1-trimethylhydrazinium (cationic and exists as a variety of salts e.g. 1,1,1-trimethylhydrazinium iodide) Tetramethylhydrazine 1,1,2,2-tetramethylhydrazine 1,1,1,2-tetramethylhydrazinium (cationic and exists as a variety of salts) Pentamethylhydrazinium (cationic and exists as a variety of salts) Hexamethylhydrazinediium (dication, exists as a variety of salts)
