Methylhydrazines

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)
