  • Applications

    n-PROPYL NITRATE (CAS 627-13-4) is primarily used as a solvent and plasticizer in nitrocellulose-based coatings and inks; it also serves as a precursor for the synthesis of nitrate ester compounds and related derivatives; it is employed as a solvent for industrial adhesives, resins, and varnishes; and it may be used as a specialty cleaning or surface-preparation solvent in certain manufacturing workflows.
