An NMR spectroscopic method for the determination of mixtures of trimethoprim and sulfamethoxazole is described. Spectra are determined in dimethylsulfoxide-d6, containing 1,4-dinitrobenzene as an internal standard. Both synthetic mixtures and commercial formulations were assayed, and the results were compared to those obtained using the BP procedure.
描述了一种用于测定甲氧苄啶和磺胺甲恶唑混合物的核磁共振光谱法。光谱在含有1,4 - 二硝基苯作为内标的氘代二甲亚砜中测定。对合成混合物和市售制剂均进行了分析,并将结果与采用英国药典方法获得的结果进行了比较。
