Product Application Of 4-Methyl-2-pentanone CAS#108-10-1
Methyl isobutyl ketone (hexone, isobutyl methyl ketone, 4-methyl-2-pentanone) is an organic solvent similar in structure and use to methyl butyl ketone. In addition to its use as a solvent for paints, lacquers, and varnishes, methyl isobutyl ketone is used in extraction processes and as a denaturant for rubbing alcohol. Methyl isobutyl ketone is also used as a synthetic flavoring in some varieties of rum, candy, and cheese. Unlike methyl butyl ketone, methyl isobutyl ketone has not been found to occur naturally.
