产品介绍 Description

N-乙基-N-(3-磺丙基)-3-甲基苯胺 钠盐（3-(Ethyl[3-methylphenyl]amino)-1-propanesulfonic acid 3-(n-ethyl-3-methylanilino)propanesulfonic acid sodium salt 40567-80-4 N-Ethyl-N-(3-sulfopropyl)-3-methylaniline,sodium salt (TOPS) n-ethyl-n-(3-sulfopropyl)-3-methylaniline, sodium salt n-ethyl-n-sulfopropyl-3-toluidine sodium salt n-ethyl-n-sulfopropyl-m-toluidine sodium salt n-ethyl-n-sulphopropyl-m-toluidine, sodium salt sodium 3-(n-ethyl-3-methylanilino)propanesulfonate sodium n-ethyl-n-(3-sulfopropyl)-m-toluidine tops tops, sodium salt）是药物分析与质量控制领域常用的药物标准品，CAS 号 40567-80-4。分子式 C12H24NO3S Na。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。

依据分子式为 C12H24NO3S Na 的N-乙基-N-(3-磺丙基)-3-甲基苯胺 钠盐结构特征，其分子内含酰胺类，含砜基，羧酸类，含羟基，含醚键，这意味着该化合物在红外光谱中会呈现特征性的官能团伸缩振动信号。分子量 285.38 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。由于碳链较长，脂溶性良好，该化合物在Octanol-Water分配系数测试中倾向于有机相。 化学式为 C12H24NO3S Na 的N-乙基-N-(3-磺丙基)-3-甲基苯胺 钠盐（3-(Ethyl3-methylphenylamino)-1-propanesulfonic acid 3-(n-ethyl-3-methylanilino)propanesulfonic acid sodium salt 40567-80-4 N-Ethyl-N-(3-sulfopropyl)-3-methylaniline,sodium salt (TOPS) n-ethyl-n-(3-sulfopropyl)-3-methylaniline, sodium salt n-ethyl-n-sulfop

应用场景：从实际应用出发，N-乙基-N-(3-磺丙基)-3-甲基苯胺 钠盐（CAS 40567-80-4）在化学分析中作为关键的基准对照物质。 推荐以N-乙基-N-(3-磺丙基)-3-甲基苯胺 钠盐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2-8°C冷藏保存，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
