DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Chromatog. sepn. on silica gel thin layers with (:5) BuOH-HOAc-H2O as developing solvent was used to analyze for urea [57-13-6] and .gamma.-phenylpropanol [122-97-4] impurities in . 122-97-4 and 57-13-6 which are cas registry numbers of chemicals are mentioned.gamma.-phenylpropyl carbamate [Ph(CH2)3O2CNH2] [673-31-4] samples. Urea spots were revealed with p-dimethylaminobenzaldehyde and phenylpropanol and phenylpropyl carbamate spots by exposure to 254 nm light. .gamma.-Phenylpropanol was not detected in any of the 10 samples tested, and urea was detected in 4. .
