    Product Description

    Methyl Isobutyl Ketone (MIBK) is a medium-boiling ketone solvent identified by CAS 108-10-1 and EC/EINECS 203-550-1.

    Synonyms: 4-Methyl-2-pentanone; MIBK; Isopropylacetone; 4-Methylpentan-2-one; Hexone.

    CAS: 108-10-1.

    Molecular formula: C₆H₁₂O.

    Molecular weight: 100.16.

    EC number: 203-550-1.

    It is a clear, colorless, low-viscosity liquid with a mild characteristic odor.

    Typical properties include melting point about -84 °C, boiling range about 116-118 °C, density about 0.80 g/mL at 25 °C, refractive index about 1.395-1.397 at 20 °C, and flash point about 17 °C.

    MIBK is used as a solvent for coatings, inks, lacquers, varnishes and adhesives.

    It is also used in extraction and separation processes for metal refining and petrochemical dewaxing, in pharmaceutical and agrochemical processing, and as a chemical intermediate.

    MIBK is flammable: store in tightly closed containers away from heat, sparks, open flames and strong oxidizers; use grounding, vapor controls and PPE.

    Confirm assay, water content, color, acidity and residue after evaporation.

    Confirm the current product-specific specification.

    Confirm packaging with the requested quantity and destination requirements.

    Document requirements should be confirmed from the current specification, SDS, COA, or other product-specific files.

    Regulated-use suitability must be confirmed separately with current product-specific documentation.
