Description
Methyl isoamyl ketone, commonly abbreviated as MIAK and also known as isobutylacetone or 5-methyl-2-hexanone, is a ketone solvent with CAS number 110-12-3 and EC number 203-737-8. It carries no assigned E-code. It belongs to the broader family of aliphatic ketone solvents used across industrial and specialty chemical applications.
In coatings and printing inks, MIAK dissolves nitrocellulose and acrylic resins at moderate evaporation rates, giving formulators control over film formation and flow. In metalworking fluids, it functions as a carrier solvent that improves the dispersion of active additives. Its mild fruity character also supports flavoring applications in food-grade contexts.
MIAK is supplied as a liquid and is available in industrial grades compliant with REACH registration requirements. Procurement teams should confirm FCC-grade availability for food and flavor applications. Standard packaging includes drums and IBC containers, with bulk options subject to supplier confirmation.
