CAS号 EC号 Hill配方 化学配方 摩尔质量 级别值 67-56-1 200-659-6 CH₄O CH₃OH 32.04 g/mol Reag. Ph Eur 描述 产品目录编号 106007 同义词 MeOH, Hydroxymethane, Methyl alcohol, Carbinol 概述 With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved. 产品信息 CAS号 67-56-1 EC索引编号 603-001-00-X EC号 200-659-6 级别 Reag.
