  • Applications

    3-Methyl-1-(1-(2-methylpropoxy)ethoxy)butane (CAS 75048-15-6) is a di-ether glycol ether commonly used as a solvent and co-solvent in industrial formulations. In coatings and inks, it aids resin and pigment solubility and improves flow, leveling, and film formation. It is also employed in cleaning formulations and degreasers for dissolving organic contaminants. In adhesive and polymer processing, it can function as a processing aid and solvent to assist formulation, viscosity control, and component compatibility. In cosmetics and personal care products or fragrance formulations, it may serve as a solvent or carrier for fragrance ingredients, subject to regulatory limits. Additionally, it may be used as an intermediate or processing aid in organic synthesis or polymer manufacture, with usage governed by local regulations.
