Uses of Phenidone: This product is used as a photographic developer. Unlike some other developers, it has low toxicity and does not cause dermatitis upon skin contact. It also can used in organic synthesis. For example: It can react with 1-vinyl-pyrrolidin-2-one to get 1-(2-oxopyrrolidin-1-yl)-1-(5-oxo-2-phenylpyrazolidin-1-yl)ethane. This reaction needs reagent Me3SiCl by heating. The yield is 96%.
