Characterization of Impurities of 8-Chlorotheophylline using Modern analytical Techniques.

Author: UPLOADED BY-ADMIN, A. J. PATEL, S S. DESAI, S. Y. GABHE
Abstract: Two impurities present in 8-chlorotheophylline were separated by a gas chromatography. For the characterization of impurities GC-MS was used. The number of impurities present in the sample of 8-chlorotheophylline was also confirmed by HPTLC and HPLC. Based on mass spectral data, the structures of these impurities were characterized as N-chloro methyl derivative of 8-Chlorotheophylline and hydrated N-chloro methyl derivative of 8- Chlorotheophylline.
