盐酸苯氧丙酚胺可供口服和注射,是外周和脑血管舒张药,还有松弛血管和子宫平滑肌的效应。有多种含量测定方法。本文报道在碱性介质中,用重氮化的对氨基苯磺酸作偶合剂的分光光度法。试剂标准药物溶液:盐酸苯氧丙酚胺应符合美国药典,将本品20mg溶解在100ml蒸馏水中,制成标准溶液。重氮化的对氨基苯磺酸溶液:将新制的2%亚硝酸钠溶液20ml,逐 Phenacetophenone hydrochloride is available orally and injections, as well as peripheral and cerebral vasodilators, as well as the effects of relaxing blood vessels and uterine smooth muscle. There are a variety of determination methods. This paper reports the spectrophotometric method using diazotized p-aminobenzene sulfonic acid as a coupling agent in alkaline media. Reagents Standard drug solution: Phenacetophenone hydrochloride should be consistent with the United States Pharmacopoeia, the goods 20mg dissolved in 100ml of distilled water, made of standard solution. Diazotized sulfanilic acid solution: The new 2% sodium nitrite solution 20ml, by
