CAS号 EC号 Hill配方 化学配方 摩尔质量 68-12-2 200-679-5 C₃H₇NO HCON(CH₃)₂ 73.09 g/mol 描述 产品目录编号 102937 同义词 DMF, N,N-Dimethylmethanamide, Formic acid dimethylamide 概述 Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS. 产品信息 CAS号 68-12-2 EC索引编号 616-001-00-X EC号 200-679-5 Hill配方 C₃H₇NO 化学配方 HCON(CH₃)₂ Molar Mass 73.09 g/mol HS代码 2924 19 00 结构配方图像 理化信息 沸点 153 °C (1013 hPa) 密度 0.94 g/cm³ (20 °C) 爆炸极限 2.2 - 16 %(V) 闪点 58 °C 燃点 410 °C 熔点 -61 °C pH值 7 (200 g/l, H₂O, 20 °C) 蒸汽压力 3.77 hPa (20 °C) 折射系数 1.43 溶解度 (20 °C) 可溶 毒性学信息 LD 50口服 LD50 Rat 3010 mg/kg LD 50皮下注射 LD50 Rabbit 1500 mg/kg GHS安全信息 危害性图示
