| Physical and Chemical Properties | Sulfate of methyl hydrazine. Methyl hydrazine is a clear liquid, boiling point of 87.5 ℃, strong reducibility, easy to burn in contact with strong oxidant, flash point of 70 ℃, strong irritation to skin and mucosa, and shows strong physiological toxicity; methyl hydrazine sulfate is a white flake crystal with a melting point of 141-142 ℃, which is safe to use. |
| Risk Codes | R23/24/25 - Toxic by inhalation, in contact with skin and if swallowed. R40 - Limited evidence of a carcinogenic effect |
