CAS号 EC号 Hill配方 化学配方 摩尔质量 75-05-8 200-835-2 C₂H₃N CH₃CN 41.05 g/mol 描述 产品目录编号 100029 同义词 ACN, Methyl cyanide, Ethyl nitrile, Cyanomethane 概述 LiChrosolv® hypergrade is accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv® hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly. 产品信息 CAS号 75-05-8 EC索引编号 608-001-00-3 EC号 200-835-2 Hill配方 C₂H₃N 化学配方 CH₃CN Molar Mass 41.05 g/mol HS代码 2926 90 95 结构配方图像 理化信息 沸点 81.6 °C (1013 hPa) 密度 0.786 g/cm³ (20 °C) 爆炸极限 3.0 - 17 %(V) 闪点 2 °C 燃点 524 °C 熔点 -45.7 °C 蒸汽压力 97 hPa (20 °C) 折射系数 1.34 溶解度 (20 °C) 可溶 GHS安全信息 危害性图示
