应用场景:3-((2-(吡咯烷-1-基)苯基)氨基)苯并 d 异噻唑1,1-二氧化物(3-((2-(Pyrrolidin-1-yl)phenyl)amino)benzo d isothiazole 1,1-dioxide)作为药物标准品,在化学分析分析领域承担着重要的角色。 推荐以3-((2-(吡咯烷-1-基)苯基)氨基)苯并 d 异噻唑1,1-二氧化物配制标准系列工作溶液,用于建立标准曲线实现外标法定量。 建议使用甲醇/乙腈(1:1)为溶剂配制储备溶液,根据检测灵敏度需求逐级稀释。 使用建议: - 称量前将样品在干燥器内平衡至室温(约30分钟); - 储备溶液建议用甲醇/乙腈(1:1)配制
