Chemical compound

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.

Phenidone is Ilford's trademark for this material which was first prepared in 1890. It was not until 1940 that Dr. J. D. Kendall, in the laboratories of Ilford Limited, discovered the photographic reducing properties of this chemical. However, large scale manufacturing of the compound did not become feasible until 1951

Preparation

Phenidone is prepared by heating phenyl hydrazine with 3-chloropropionic acid also called UMB66.
