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硫氰酸汞(II)在内的目标物的控制。 硫氰酸汞(II)（592-85-8 3JNH1DM7IF Mercuric thiocyanate Mercury dithiocyanate Thiocyanic acid, mercury(II) salt Thiocyanic acid, mercury(2+) salt (2:1) Thiocyanic acid, mercury(2+) salt EINECS 209-773-0 HSDB 1224 Mercuric sulfocyanate Mercuric sulfocyanide Mercury, bis(thiocyanate) Mercury, bis(thiocyanato)- Mercury thiocyanate Hg(SCN)2 Mercury(II) thiocyanate Mercury(II)thiocyanate UNII-3JNH1DM7IF Mercury thiocyanate Mercury thiocyanate UN1646 Pois
应用场景：从实际应用出发，硫氰酸汞(II)（CAS 592-85-8）在化学分析中作为关键的基准对照物质。 推荐以硫氰酸汞(II)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。
