产品介绍 Description

双(二苯基膦)甲烷（英文名 Bis(diphenylphosphino)methane 2071-20-7 1,1'-METHYLENEBIS[1,1-DIPHENYLPHOSPHINE;BIS(DIPHENYL PHOSPHINE)METHANE;BIS(DIPHENYLPHOSPHINO)METHANE;DPM;DPPM;METHANEDIYLBIS[DIPHENYLPHOSPHINE];METHYLENEBIS(DIPHENYLPHOSPHINE);TETRAPHENYLMETHYLENEDIPHOSPHINE;[(1,1-DIPHENYLPHOSPHINO)METHYL](DIPHENYL)PHOSPHINE;[(DIPHENYLPHOSPHANYL)METHYL]DIPHENYLPHOSPHANE GC10102，CAS 2071-20-7）属于药物标准品。分子式 C25H46P2，分子量 408.58。纯度 97%+。佳途科技作为 ISO 17034 认可的标准物质生产商，为该产品提供完整的质量文件与技术支持。

双(二苯基膦)甲烷（C25H46P2）含有有机磷。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。较高的碳氢原子比赋予该化合物良好的脂溶性，可使用正己烷或乙酸乙酯等非极性溶剂进行液-液萃取前处理。 双(二苯基膦)甲烷（Bis(diphenylphosphino)methane 2071-20-7 1,1'-METHYLENEBIS1,1-DIPHENYLPHOSPHINE;BIS(DIPHENYL PHOSPHINE)METHANE;BIS(DIPHENYLPHOSPHINO)METHANE;DPM;DPPM;METHANEDIYLBISDIPHENYLPHOSPHINE;METHYLENEBIS(DIPHENYLPHOSPHINE);TETRAPHENYLMETHYLENEDIPHOSPHINE;(1,1-DIPHENYLPHOSPHINO)METHYL(DIPHENYL)PHOSPHINE;(DIPHENYLPHOSPHANYL)METHYLDIPHENYLPHOSPHANE GC10102），CAS注册编号 2071-20

应用场景：在化学分析实验室中，双(二苯基膦)甲烷（CAS 2071-20-7）凭借其97%+的纯度做为基础物质，为定量分析提供基准参照。 推荐以双(二苯基膦)甲烷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。
