  • Applications

    1-Isopentyloxy-1-propoxypropane (CAS 238757-65-8) is used primarily as a solvent and processing aid across multiple industries; in coatings and inks it can serve as a secondary or co-solvent to improve pigment dispersion and film formation, while in cleaning and household formulations it acts as a solvent component for resins and fragrance ingredients. It may also function as an intermediate in the synthesis of specialty chemicals and as a component in polymer formulations where it contributes to viscosity control and compatibility. In perfumery and cosmetics, it is sometimes evaluated as a fragrance solvent or carrier. Its use is typically formulation-specific and subject to local regulations and formulation limits.
