产品介绍 Description

CAS 39941-51-0 对应的（39941-51-0 Uttronin A beta-D-Galactopyranoside, (3beta,5alpha,25R)-spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)- 3-O-(beta-Lycotetraosyl)-(25R)-5alpha-spirostan-3beta-ol (3beta,5alpha,25R)-Spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)-beta-D-galactopyranoside）为 CATO 佳途药物标准品产品线成员。分子式 C50H82O22，分子量 1035.17。纯度 97%+。所有批次均经 HPLC/NMR 等多项检测确认，质量稳定可溯源。

（C50H82O22）含有羧酸类，含羟基，含醚键，多环芳烃。羧基赋予其一定的酸性特征，这些物理化学性质直接决定了其标准溶液的最佳配制方案和储存策略。分子中包含芳环或共轭体系，在UV-Vis光谱中具有特征性吸收带，适用于紫外或二极管阵列检测器（DAD）的定量分析。 CAS编号 39941-51-0 对应的化合物（英文标识 39941-51-0 Uttronin A beta-D-Galactopyranoside, (3beta,5alpha,25R)-spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)- 3-O-(beta-Lycotetraosyl)-(25R)-5alpha-spirostan-3beta-ol (3beta,5alpha,25R)-Spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glu

应用场景：在化学分析实验室中，（CAS 39941-51-0）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配制，于室温保存，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。
