Stability

Incompatible with a wide variety of materials, including oxidizing agents, heavy metal oxides, dehydrating agents, alkali metals, rust, silver salts. Combustible. Contact with many materials may cause fire or explosive decomposition. May react explosively with a variety of materials, including dehydrating agents, heavy metal oxides, perchlorates. Contact with cadmium, gold, brass, molybdenum and stainless steel containing > 0.5% molybdenum may cause rapid decomposition. Vapour may explode in fire. Note the exceptionally wide explosive limits - flammable from 4 to 100% hydrazine in air. Read safety data sheet fully before use.

Toxicology
