在现行药典和法规框架下，药物标准品的合规要求中明确涉及对包括在内的目标物的控制。 CAS编号 156-56-9 对应的化合物（英文标识 156-56-9 7GB7U7M282 Hypoglycin Hypoglycine A Cyclopropanepropanoic acid, alpha-amino-2-methylene- (9CI) Cyclopropanepropionic acid, alpha-amino-2-methylene-, L-(+)- alpha-Amino-2-methylenecyclopropanepropanoic acid alpha-Aminomethylenecyclopropanepropionic acid L-alpha-Amino-beta-methylenecyclopropanepropionic acid alpha-Amino-2-methylenecyclopropanepropionic acid alpha-Amino-beta-(2-methylenecyclopropyl)propionic acid 2-Amino-

应用场景：从实际应用出发，（CAS 156-56-9）在化学分析中作为关键的基准对照物质。 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/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。
