产品介绍 Description

CATO 佳途供应的（(20S)-3|A-Acetoxypregn-5-ene-20-carboxaldehyde (3|A,20S)-20-Formyl-3-hydroxy-5-pregnene 3-O-AcetateDiscontinued (3|A,20S)-3-(Acetyloxy)pregn-5-ene-20-carboxaldehyde 10211-88-8 3|A-Acetoxy-22,23-dinorchol-5-en-24-al 3|A-Acetoxybisnor-5-cholen-22-al）为药物标准品，CAS 登记号 10211-88-8，分子式 C24H36O3，分子量 372.54。纯度 97%+。产品现货库存充足，可提供定制化规格与批次追踪服务。

化学式为 C24H36O3 的（(20S)-3|A-Acetoxypregn-5-ene-20-carboxaldehyde (3|A,20S)-20-Formyl-3-hydroxy-5-pregnene 3-O-AcetateDiscontinued (3|A,20S)-3-(Acetyloxy)pregn-5-ene-20-carboxaldehyde 10211-88-8 3|A-Acetoxy-22,23-dinorchol-5-en-24-al 3|A-Acetoxybisnor-5-cholen-22-al），其CAS登记号是 10211-88-8，分子量为 372.54 g/mol。 依据分子式为 C24H36O3 的结构特征，其分子内含甾体骨架，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 372.54 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。 推荐用于分析方法开发与验证，产品提供完整COA证书，确保ISO 1

应用场景：从实际应用出发，（CAS 10211-88-8）在化学分析中作为关键的基准对照物质。 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。 建议使用乙腈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）； - 储备溶液建议用乙腈配制，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境下尽快使用，防止吸潮影响称量准确性。
