摘要
为建立合成塞来昔布关键中间体对肼基苯磺酰胺盐酸盐的质量标准,测定对肼基苯磺酰胺盐酸盐的含量.采用高效液相色谱法,色谱柱:Agilent ZORBAX SB-C18柱(4.6×250 mm,5 µm);流动相:缓冲液(1.65 g庚烷磺酸钠置于1000 mL容量瓶中,用水溶解并稀释至刻度,用三氟乙酸调pH值至2.5)∶乙腈=88∶12;流速为1.0 mL/min;进样量为20 μL;检测波长为233 nm;柱温为25 ℃.结果显示:该中间体的峰面积与浓度呈良好的线性关系,加样平均回收率为99.77%,相对标准偏差RSD为0.40%.结果表明,该方法方便、准确、可靠,可用于测定对肼基苯磺酰胺盐酸盐的含量.
Abstract
In order to establish the quality standard for the synthesis of the key intermediate of celecoxib,and determine the content of 4-Hydrazinobenzene-1-sulfonamide hydrochloride.HPLC was performed on Agilent ZORBAX SB-C18 column(4.6×250 mm,5 μ m).Mobile phase:buffer(1.65 g sodium heptane sulfonate in 1 000 mL volumetric bottle,dissolved with water and diluted to the scale,adjusted to pH 2.5 with trifluoroacetic acid):acetonitrile=88:12;The flow rate was 1.0mL/min.The sample size was 20 µ L.The detection wavelength was 233 nm;The column temperature was 25℃.The results showed that the peak area of the intermediate had a good linear relationship with the concentration.The average recovery was 99.77%and the RSD was 0.40%.The results show that the method is convenient,accurate and reliable,and can be used to determine the content of 4-Hydrazinobenzene-1-sulfonamide hydrochloride.
