  • Applications

    1,1-Dipropoxyethane (CAS number: 105-82-8) is a dialkyl acetal derived from acetaldehyde with two propyl groups. In industry, it is primarily used as a high-boiling organic solvent for chemical synthesis and formulation processes, and as a co-solvent in coatings, inks, and adhesive formulations. It also serves as a carbonyl-protecting group (aldehyde/ketone) in multi-step syntheses to mask reactive functionality. As a precursor or intermediate in pharmaceutical and fragrance chemistry, it may be used in specialty processing and plastics-related applications, subject to formulation limits and local regulations.
