盐酸频哪醇（C25H40N2 Cl）含有含氮杂环结构，含氰基，含氯取代。卤素取代增加了化合物的密度和沸点，较高的碳氢比使其脂溶性较好，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。由于结构中存在共轭发色团，该化合物在200-400 nm区间具有显著的紫外吸收，便于HPLC-UV检测。 化学式为 C25H40N2 Cl 的盐酸频哪醇（2768-90-3 91SZ6DGY86 Quinaldine blue Quinaldine blue USAN:INN 1-Ethyl-2-(3-(1-ethyl-2(1-H)-quinolinylidene)-1-propenyl)quinolinium chloride Quinolinium, 1-ethyl-2-(3-(1-ethyl-2(1H)-quinolinylidene)-1-propenyl)-, chloride Quinolinium, 1-ethyl-2-(3-(1-ethyl-2(1H)-quinolylidene)propenyl)-, chloride (8CI) Quinolinium, 1-ethy

应用场景：从实际应用出发，盐酸频哪醇（CAS 2768-90-3）在化学分析中作为关键的基准对照物质。 推荐以盐酸频哪醇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，于室温保存，避光条件下储存； - 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。
