67-56-1	200-659-6	CH₄O	CH₃OH	32.04 g/mol	Reag. Ph Eur

Description
Catalogue Number	106007
Synonyms	MeOH, Hydroxymethane, Methyl alcohol, Carbinol
Overview	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.
