Condensation of salicylaldehyde with hydrazine.
Two different compounds, salicylaldehyde hydrazone and salicylaldazine, are formed by the condensation of salicylaldehyde and hydrazine, as shown by the difference in their melting points, solubilities, elemental analysis and infrared spectra. The earlier work of Feigl and Terentev et al. on the use of these compounds in detection of hydrazine has been reviewed and found to be misleading; the resulting confusion has been resolved.
