ABSTRACT
Objective To establish a gas chromatography ( GC) method for determination of aniline,2-aminophenol and 4-aminophenol in mesalamine sustained release granules. Methods An HP-5 (10 m×0.53 mm,2.65 μm) capillary GC column was adopted. The carrier gas was high purity nitrogen at a flow rate of 15 mL.min-1 . The inlet temperature was controlled at 280 ℃ and the FID detector temperature was 300℃. The oven temperature was initially held at 70℃ for 2 min and was then programmed to 150 ℃ at 10℃.min-1 and held for 6 min. Results A good resolution was obtained between the peaks of the 3 impurities at chromatographic conditions above. The recoveries of aniline, 2-aminophenol and 4-aminophenol were among 98.04% to 103.00%. The precision and linearity equations were good. Conclusion The method can be adopted for the quality control of mesalazine sustained release granules.
