产品介绍 Description

（[2-oxo-2-[(2S,4S)-2,5,12-trihydroxy-7-methoxy-4-[[(2S,4R,6S,7S,9R,10S)-10-methoxy-6-methyl-5,8,11-trioxa-1-azatricyclo[7.4.0.0²⁷]tridecan-4-yl]oxy]-6,11-dioxo-3,4-dihydro-1H-tetracen-2-yl]ethyl] N-[2-[[4-[[(2S)-2-[[(2S)-2-[3-[2-[2-[2-[2-[3-(2,5-dioxopyrrol-1-yl)propanoylamino]ethoxy]ethoxy]ethoxy]ethoxy]propanoylamino]-3-methyl-butanoyl]amino]-5-ureido-pentanoyl]amino]phenyl]methoxycarbonyl-methyl-amino]ethyl]-N-methyl-carbamate）是药物分析与质量控制领域常用的药物标准品，CAS 号 2259318-52-8。分子式 C74H98N10O27，分子量 1559.62。纯度 97%+。CATO 佳途拥有 130,000+ 标准品现货目录，可一站式满足配套采购需求。

在现行药典和法规框架下，药物标准品的合规要求中明确涉及对包括在内的目标物的控制。 CAS编号 2259318-52-8 对应的化合物（英文标识 2-oxo-2-(2S,4S)-2,5,12-trihydroxy-7-methoxy-4-(2S,4R,6S,7S,9R,10S)-10-methoxy-6-methyl-5,8,11-trioxa-1-azatricyclo7.4.0.0²⁷tridecan-4-yloxy-6,11-dioxo-3,4-dihydro-1H-tetracen-2-ylethyl N-2-4-(2S)-2-(2S)-2-3-2-2-2-2-3-(2,5-dioxopyrrol-1-yl)propanoylaminoethoxyethoxyethoxyethoxypropanoylamino-3-methyl-butanoylamino-5-ureido-pentanoylaminophenylmethoxycarbonyl-methyl-aminoethyl-N-methyl-carb

应用场景：在化学分析实验室中，（CAS 2259318-52-8）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。
