CAS号 EC号 Hill配方 化学配方 摩尔质量 67-68-5 200-664-3 C₂H₆OS (CH₃)₂SO 78.13 g/mol 描述 产品目录编号 102950 同义词 Methanesulfinylmethane, Methyl sulfoxide, Dimethyl(oxido)sulfur, DMSO 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 67-68-5 EC号 200-664-3 Hill配方 C₂H₆OS 化学配方 (CH₃)₂SO Molar Mass 78.13 g/mol HS代码 2930 90 99 结构配方图像 理化信息 沸点 189 °C (1013 hPa) 密度 1.10 g/cm³ (20 °C) 爆炸极限 1.8 - 63.0 %(V) 闪点 87 °C 燃点 300 - 302 °C 熔点 18.4 °C 饱和浓度（空气） 8.0 g/m³ (20 °C) 蒸汽压力 0.6 hPa (20 °C) 运动粘度 2.14 mm²/s 折射系数 1.48 (20 °C) 溶解度 1000 g/l (20 °C) 毒性学信息 LD 50口服 LD50 Rat 28300 mg/kg LD 50皮下注射 LD50 Rat 40000 mg/kg GHS安全信息 RTECS PV6210000 储存类别 10 - 13 其它液体及固体 WGK WGK 1 轻度的水危害 一次性 1
