产品介绍 Description

CAS 2632-13-5 对应的2-溴-4′-甲氧基苯乙酮（2-Bromo-1-(4-methoxyphenyl)ethanone alpha-bromo-4-methoxyacetophenone protein tyrosine phosphatase inhibitor ii 4'-methoxyphenacyl bromide 2-bromo-1-(4-methoxy-phenyl)-ethanone omega-bromo-p-methoxy acetophenone 2-bromo-4'-methoxy acetophenone a-bromo-p-methoxyacetophenone ethanone, 2-bromo-1-(4-methoxyphenyl)- 4-methoxy phenacyl bromide 2-bromo-4'-methoxyacetophenone 2-bromo-1-(4-methoxyphenyl)ethan-1-one ethanone, 2-bromo-1-(4-methoxyphenyl) p-methoxyphenacyl bromide 4-methoxyphenacyl bromide a-bromo-4-methoxyacetophenone 1-(2-bromo-4-methoxyphenyl)ethanone ?-Bromo-4-methoxyacetophenone 2632-13-5）为 CATO 佳途药物标准品产品线成员。分子式 C9H9BrO2，分子量 229.07。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。

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 2632-13-5 对应的化合物2-溴-4′-甲氧基苯乙酮（英文标识 2-Bromo-1-(4-methoxyphenyl)ethanone alpha-bromo-4-methoxyacetophenone protein tyrosine phosphatase inhibitor ii 4'-methoxyphenacyl bromide 2-bromo-1-(4-methoxy-phenyl)-ethanone omega-bromo-p-methoxy acetophenone 2-bromo-4'-methoxy acetophenone a-bromo-p-methoxyacetophenone ethanone, 2-bromo-1-(4-

应用场景：在化学分析实验室中，2-溴-4′-甲氧基苯乙酮（CAS 2632-13-5）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2-溴-4′-甲氧基苯乙酮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，密闭保存防止挥发条件下储存； - 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。
