5-tert-Butyl-5-phenylhydantoin is a chemical compound with the molecular formula C16H18N2O2. It is a white crystalline solid that is soluble in organic solvents such as ethanol and acetone. 5-tert-Butyl-5-phenylhydantoin is primarily used as a chiral stationary phase in gas chromatography for the separation of enantiomers, particularly in the analysis of pharmaceuticals and agrochemicals. Its unique structure, featuring a tert-butyl group and a phenyl group, contributes to its selectivity and stability in chiral separations. The compound is also of interest in the field of asymmetric synthesis due to its potential applications in the preparation of enantiomerically pure compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 7641-32-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7641-32:
(6*7)+(5*6)+(4*4)+(3*1)+(2*3)+(1*2)=99
99 % 10 = 9
So 7641-32-9 is a valid CAS Registry Number.

Synthesis, structure, and solvatochromic properties of pharmacologically active 5-substituted 5-phenylhydantoins

Trisovic, Nemanja,Valentic, Natasa,Erovic, Marko,Dakovic-Sekulic, Tatjana,Uscumlic, Gordana,Juranic, Ivan

, p. 1227 - 1234 (2011)

A series of 5-substituted 5-phenylhydantoins was synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability and solvent-solute hydrogen-bonding interactions were analyzed by means of the linear solvation energy relationship concept proposed by Kamlet and Taft. The lipophilicities of the investigated hydantoins were estimated by calculation of their log P values. The quantitative relationship between the ratio of the contributions of specific solvent interactions and the corresponding lipophilicity parameter is discussed. The correlation equations were combined with the corresponding ED50 values and different physicochemical parameters to generate new equations that demonstrate the reasonable relationships between solute-solvent interactions and the structure-activity parameters. In order to determine a spectroscopic assignment of the absorption bands in different solvents, quantum chemical calculations were done. Springer-Verlag 2011.
