Product Overview
Methyl Isobutyl Ketone (MIBK) ACS Grade is a high-purity, colorless, flammable liquid solvent. Chemically known as 4-Methyl-2-pentanone, this ketone offers high solvency for resins, gums, and nitrocellulose, combined with moderate volatility. This product is manufactured to meet or exceed American Chemical Society (ACS) Reagent specifications, ensuring strict control over assay, water content, and residue levels.
The ACS Grade designation makes this MIBK suitable for sensitive analytical and industrial applications, including use as a mobile phase in HPLC, extraction in pharmaceutical manufacturing, and solvent applications in high-performance coatings. Its low acidity (≤0.0005 meq/g) and controlled water content support consistent reaction rates and prevent baseline drift in chromatographic analysis. MIBK is slightly soluble in water but miscible with most organic solvents.

Safety & Handling
Methyl Isobutyl Ketone is a flammable liquid and vapor (Class 3). Store in a cool, dry, well-ventilated area away from heat, sparks, open flames, and strong oxidizers. Keep containers bonded and grounded during transfer to prevent static discharge. Personal Protective Equipment (PPE), including solvent-resistant gloves and safety goggles, is required during handling. Ensure adequate ventilation to maintain vapor levels below exposure limits.
