产品介绍 Description

本产品为药物标准品（(S)-N-[(2S,4S,5S)-5-(Dibenzylamino)-4-hydroxy-1,6-diphenylhexan-2-yl]-3-methyl-2-(2-oxotetrahydropyrimidin-1(2H)-yl)butanamide (|AS)-N-[(1S,3S,4S)-4-[Bis(phenylmethyl)amino]-3-hydroxy-5-phenyl-1-(phenylmethyl)pentyl]tetrahydro-|A-(1-methylethyl)-2-oxo-1(2H)-pyrimidineacetamide 192726-04-8，CAS 192726-04-8），分子式 C41H50N4O3，分子量 646.86。纯度 97%+。适用于分析方法开发、方法验证及日常质检，CATO 提供全程冷链与全球配送。

依据分子式为 C41H50N4O3 的结构特征，其分子内含含氮杂环结构，酰胺类，含羟基，含醚键，这意味着该化合物在紫外光谱中会呈现特征性的吸收带。分子量 646.86 g/mol 这一参数对质谱检测中的分子离子峰识别具有直接参考价值。分子中的氮原子赋予该化合物一定的碱性特征，在酸性流动相条件下可被有效质子化。 CAS编号 192726-04-8 对应的化合物（英文标识 (S)-N-(2S,4S,5S)-5-(Dibenzylamino)-4-hydroxy-1,6-diphenylhexan-2-yl-3-methyl-2-(2-oxotetrahydropyrimidin-1(2H)-yl)butanamide (|AS)-N-(1S,3S,4S)-4-Bis(phenylmethyl)amino-3-hydroxy-5-phenyl-1-(phenylmethyl)pentyltetrahydro-|A-(1-methylethyl)-2-oxo-1(2H)-pyrimidineacetamide 192726-04-8），化学式 C41H50N4O3，相对分子质量

应用场景：在化学分析实验室中，（CAS 192726-04-8）凭借其97%+的纯度做为基础物质，为定量分析提供基准参照。 推荐以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，于阴凉处（≤25°C）保存，避光，密封防潮条件下储存； - 低浓度工作液（<10 μg/mL）建议当天配制使用，不宜长期存放； - 开启安瓿瓶/西林瓶后应在干燥环境下尽快使用，防止吸潮影响称量准确性。
