  • Applications

    2,4-Dimethyl-2-pentanol (CAS 625-06-9) is a tertiary alcohol used primarily as a solvent and chemical intermediate in various industrial contexts. In practice it serves as a solvent and reaction medium in industrial manufacturing, a co-solvent or carrier in coatings and inks, and a component in cleaning formulations. It is also utilized as an intermediate for the synthesis of other chemicals, such as esters and related compounds. Additionally, it may be evaluated for use as a fragrance note or odorant in perfumery, and can act as a processing aid or solvent in polymer and plastics formulations, subject to formulation limits and regulations.
