$116.00
Methyl Alcohol, Exceeds A.C.S Specifications, HPLC Grade is a colorless, flammable substance used in chemical labs as a polar protic solvent in organic synthesis, as well as a carrier (mobile phase) solvent in high pressure liquid chromatography (HPLC). Less expensive than Acetonitrile, the popularity Methyl Alcohol HPLC continues to grow, especially in reversed phase HPLC.
All HPLC and Ultra-pure solvents offered by Spectrum are glass distilled, submicron filtered, and undergo rigorous specification testing to insure accurate, repeatable results.
