Methylhydrazines Explained

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)
