The IUPAC name of Phenidone is 1-phenylpyrazolidin-3-one. With the CAS registry number 92-43-3, it is also named as 2-Pyrazolin-3-ol, 1-phenyl-; Fenidon. In addiotion, this chemical is light beige powder or crystals which is soluble in hot water. And it is stable, but light sensitive. It is also incompatible with strong acids, strong oxidizing agents, strong bases. 

The other characteristics of this product can be summarized as: (1)ACD/LogP: 0.19; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 0.19; (4)ACD/LogD (pH 7.4): 0.18; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 30.05; (8)ACD/KOC (pH 7.4): 29.82; (9)#H bond acceptors: 3; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 1; (12)Index of Refraction: 1.578; (13)Molar Refractivity: 45.32 cm³; (14)Molar Volume: 136.4 cm³; (15)Polarizability: 17.96×10^-24 cm³; (16)Surface Tension: 45.2 dyne/cm; (17)Enthalpy of Vaporization: 57.49 kJ/mol; (18)Vapour Pressure: 0.000393 mmHg at 25°C; (19)Rotatable Bond Count: 1; (20)Tautomer Count: 3; (21)Exact Mass: 162.079313; (22)MonoIsotopic Mass: 162.079313; (23)Topological Polar Surface Area: 32.3; (24)Heavy Atom Count: 12.

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%.

When you are using this chemical, please be cautious about it as the following:
It is harmful if swallowed. And it is toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment, so people should avoid releasing to the environment. Refer to special instructions / safety data sheets.

People can use the following data to convert to the molecule structure.
1. SMILES: O=C2NN(c1ccccc1)CC2;
2. InChI: InChI=1/C9H10N2O/c12-9-6-7-11(10-9)8-4-2-1-3-5-8/h1-5H,6-7H2,(H,10,12).
