AB  - A straightforward quantitative method for gas chromatography-mass spectrometry determination of isosorbide 5-mononitrate (ISSMN) and its related impurities such as isosorbide (IS), isosorbide diacetate (ISDA) and isosorbide 2-acetate-5-nitrate (IS2A5N) in raw materials as well as in dosage formulations is developed. The recovery of these materials was found to be 100.4 +/- 2.4, 99.3 +/- 4.7, 97.8 +/- 5.2 and 100.1 +/- 3.1%, while the detection limits were 27.2, 1.26, 1.02 and 0.78 mu g in dosage formulations for ISSMN, ISDA, IS2A5N, and IS, respectively. The applicability of the method was tested by analysing three different formulations of ISSMN. (C) 1997 Elsevier Science B.V.

AB  - The proposed method is based on coloured hydrazone formation with 1,4-dihydrazinophthalazine as a reagent. Heating at 85 degrees C for 2 h was found necessary to ensure optimal hydrazone formation in the presence of hydrochloric acid. The yellow hydrazone product has an absorption maximum at 380 nm. A linear relationship between absorbance and concentration was established in the concentration range 3.19 x 10(-6)-3.19 x 10(-5) mol l(-1) (the regression equation was y = 0.013 167 3 + 0.019 025 9x; correlation coefficient r = 0.9991; n = 6). The detection limit was 1.2 mu g ml(-1) (molar absorptivity found was 1.97 x 10(4) l mol(-1) cm(-1)). The reliability of the proposed method was checked at three different concentrations; the relative standard deviation (RSD) varied from 1.03 to 2.01%. The described method applied to the determination of desoximetasone in ointment gave precise and reproducible results; the recovery was 98.55% with RSD = 2.40% (n = 10).
