Description
Catalogue Number	101988
Synonyms	Butan-1-ol, n-Butyl alcohol, BuOH
Description	1-Butanol
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.
