化学式为 C41H70NO8P 的18:3 PE(34813-40-6 C5Z6T7TC8Z 1,2-Dilinolenoyl-sn-glycero-3-phosphatidylethanolamine UNII-C5Z6T7TC8Z 9,12,15-Octadecatrienoic acid, 1,1'-((1R)-1-((((2-aminoethoxy)hydroxyphosphinyl)oxy)methyl)-1,2-ethanediyl) ester, (9Z,9'Z,12Z,12'Z,15Z,15'Z)- 1,2-Di-9,12,15-octadecatrienoyl-sn-glycero-3-phosphorylethanolamine 1,2-Dilinolenoyl-sn-glycero-3-phosphatidylethanolamine, (R)-),其CAS登记号是 34813-40-6,分子量为 735.97 g/mol。 受分子结构中含氮杂环结构,酰胺类,含磷酸酯基,含羟基,含醚键的影响,18:3 PE表现为类白色至淡黄色无定形粉末。其固体形态的物理化学属性

应用场景:从实际应用出发,18:3 PE(CAS 34813-40-6)在化学分析中作为关键的基准对照物质。 推荐以18:3 PE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。
