Products Description of 4-Methyl-2-pentanone CAS #108-10-1
4-Methyl-2-pentanone, commonly known as methyl isobutyl ketone (MIBK), is extensively utilized as a solvent in the chemical and pharmaceutical sectors, the separation and recovery of nuclear fission products, and scientific research experiments. Commercial 4-methyl-2-pentanone typically has a purity of ≥99%, with trace impurities including alcohols, acidic compounds, and water. This reagent serves as a solvent for nitrocellulose, lacquers, and specific polymers and resins. Additionally, it acts as a reactant in the synthesis of 2-(1-hydroxy-3-methylbutynyl)-1H-indene-1,3(2H)-dione.

Product Application of 4-Methyl-2-pentanone CAS #108-10-1
It serves as an intermediate in the production of pharmaceuticals and dyes. Mitosil, a pesticide derived from o-chlorobenzaldehyde, is effective in controlling mites on dry-field crops and fruit trees. O-chlorobenzaldehyde can undergo oximation to yield o-chlorobenzaldehyde oxime, which can be further chlorinated to produce o-chlorobenzaldoxime chloride—both of these compounds act as pharmaceutical intermediates.
