Phenidone (1-phenyl-3-pyrazolidinone) is an organic chemical compound whose primary use is as a photographic developer. It has five to ten times the developing power as Metol. It also has low toxicity and, unlike some other developers, does not cause dermatitis upon skin contact.[1]
[edit] Preparation
Phenidone is prepared by heating phenyl hydrazine with 3-chloropropionioc acid.[1]
