4-Methyl-2-pentanol

4-Methyl-2-pentanol (IUPAC name: 4-methylpentan-2-ol) or methyl isobutyl carbinol (MIBC) is an organic chemical compound used primarily as a frother in mineral flotation and in the production of lubricant oil additives such as Zinc dithiophosphate. It is also used as a solvent, in organic synthesis, and in the manufacture of brake fluid and as a precursor to some plasticizers. It is an acetone derivative in liquid state, with limited solubility in water but generally miscible with most organic solvents.
