Use | diphenylthiocarbazine is a hydrazine derivative which can be used as a pharmaceutical synthesis intermediate. tests for bismuth, cadmium, cobalt, copper, lead, silver, nickel, magnesium, and mercury. |
production method | phenylhydrazine is reacted with carbon disulfide to obtain phenylhydrazine dithiocarbamate phenylhydrazine salt, which is heated to release hydrogen sulfide and ammonia, conversion to diphenylthiocarbazine in 60-75% yield. |
