酸性染料直接滴定法测定盐酸哌吡(艹卓)酮的含量

ACID DYE DIRECT TITRATION FOR PIRENZEPINF

  • 摘要: 盐酸哌吡(艹卓)酮(pirenzepine)化学名为5,6-二氢-6-氧代-11-(4-甲基-1-哌嗪基)乙酰基吡啶并2,3-61,4苯并二氮杂(艹卓)盐酸盐。本品是一种白色结晶性粉末,无臭、味苦、具引湿性,在水中易溶,乙醇中略溶。本品为抗胆碱药,对胃粘膜毒蕈胆碱受体具有高度选择性拮抗作用,减少胃酸的作用类似阿托品。关于其分析方法的研究报道很少。本文采用了酸性染料直接滴定法测定含量,并与紫外分光光度法进行了比较,结果较为满意。在一定PH条件下,有机碱类(B)可与氢离子结合成BH~ ,某些酸性染料解离为阴离子

     

    Abstract: Pirenzepine was determined by the acid dye direct titration.The results were in good agreement with those obtained by spectrophotometry.The average recovery of pirenzepine was 99.38%(n=9),and a variationcoefficient was 0.33%.
