  • Applications

    2,4-Dimethylhexan-2-ol (CAS 42328-76-7) is a branched C8 tertiary alcohol used as a medium‑polarity, high‑boiling solvent/co‑solvent for resins, coatings, inks, and adhesives; a coalescent and coupling aid in waterborne systems; an extractant and phase modifier in solvent extraction; a synthetic intermediate to esters (acrylates/methacrylates, carboxylates, phosphates) for UV‑curable resins, plasticizers, and flame‑retardant additives; a feedstock for ethoxylated/sulfonated derivatives serving as surfactants in cleaners, metalworking fluids, and agrochemical emulsions; a component or carrier for lubricant additive packages and a precursor to specialty lubricant esters; a frothing agent in mineral flotation akin to other branched C6–C8 alcohols; and a versatile intermediate in organic synthesis (dehydration to branched olefins for alkylation, formation of esters/carbamates to install the 2,4‑dimethylhexyl group), with specific use determined by sector regulations and safety requirements.
