A method for the quantitative analysis of phenylbutazone in tablets using NMR is reported. The method is both accurate and precise. Using synthetic mixtures, the mean recovery value +/- SD was 100.5 +/- 0.86%. The NMR results of commercial preparations are compared with those obtained by the USP XX procedure. The NMR spectrum, in addition, provides a very specific means of identification for phenylbutazone.
报道了一种使用核磁共振（NMR）对片剂中保泰松进行定量分析的方法。该方法既准确又精密。使用合成混合物时，平均回收率值±标准差为100.5±0.86%。将市售制剂的核磁共振结果与通过美国药典XX程序获得的结果进行了比较。此外，核磁共振谱为保泰松提供了一种非常特异的鉴别方法。
