CAS Number. 627-70-3 ... It is an intermediate in some hydrazine manufacturing processes. Synthesis. Acetone azine can be ...
Acetone hydrazone can be produced on large scale by reaction of acetone azine with hydrazine, a more convenient reaction than direct reaction of acetone and hydrazine. [3] Likewise, it is susceptible to disproportionation to revert to acetone azine and hydrazine, especially in the presence of water.
When derived from hydrazine itself, hydrazones condense with a second equivalent of a carbonyl to give azines: [11] R 2 C=N−NH 2 + R 2 C=O → R 2 C=N−N=CR 2 + H 2 O. Hydrazones are intermediates in the Wolff–Kishner reduction. Hydrazones are reactants in hydrazone iodination, the Shapiro reaction, and the Bamford–Stevens reaction to ...

Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
Aerozine 50 is more stable than hydrazine alone, and has a higher density and boiling point than UDMH alone. Pure hydrazine has a higher performance than Aerozine 50, but an inconvenient freezing point of 2 °C. [3] A mix of hydrazine and UDMH has a far lower freezing point due to freezing-point depression.
Later randomized controlled trials failed to find any improvement in survival, [27] [28] For example, in a trial of the treatment of advanced lung cancer, with either cisplatin and vinblastine or these drugs plus hydrazine sulfate, saw complete tumor regression in 4% of the hydrazine group, versus 3% in the control group, and tumor progression ...
