产品介绍 Description

钙镁试剂（3147-14-6 0A3KVV9HZC Calmagite 3-Hydroxy-4-((6-hydroxy-m-tolyl)azo)-1-naphthalenesulfonic acid 3-Hydroxy-4-(6-hydroxy-m-tolylazo)naphthalene-1-sulphonic acid 1-Naphthalenesulfonic acid, 3-hydroxy-4-((6-hydroxy-m-tolyl)azo)- (8CI) 1-Naphthalenesulfonic acid, 3-hydroxy-4-(2-(2-hydroxy-5-methylphenyl)diazenyl)- 1-Naphthalenesulfonic acid, 3-hydroxy-4-((2-hydroxy-5-methylphenyl)azo)- EINECS 221-563-0 NSC 299391 UNII-0A3KVV9HZC）是药物分析与质量控制领域常用的药物标准品，CAS 号 3147-14-6。分子式 C17H30N2O5S，分子量 374.50。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。

本品定值报告包含以下质量控制信息： - 主成分含量：97%+； - 水分/残留溶剂：通过卡尔费休（KF）和热重分析（TGA）测定并校正； - 定值方法：HPLC-DAD面积归一化法、qNMR法、DSC法等正交验证； - 不确定度：扩展不确定度（k=2）包含测量重复性、均匀性和稳定性分量。 CAS编号 3147-14-6 对应的化合物钙镁试剂（英文标识 3147-14-6 0A3KVV9HZC Calmagite 3-Hydroxy-4-((6-hydroxy-m-tolyl)azo)-1-naphthalenesulfonic acid 3-Hydroxy-4-(6-hydroxy-m-tolylazo)naphthalene-1-sulphonic acid 1-Naphthalenesulfonic acid, 3-hydroxy-4-((6-hydroxy-m-tolyl)azo)- (8CI) 1-Naphthalenesulfonic acid, 3-hydroxy-4-(2-(2-hydroxy-5-methylphenyl)diazeny

应用场景：在化学分析实验室中，钙镁试剂（CAS 3147-14-6）凭借其97%+的纯度做为基础物质，为定量分析提供基准参照。 推荐以钙镁试剂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境下尽快使用，防止吸潮影响称量准确性。
