  • Applications

    Pimelic acid (CAS 111-16-0) is primarily used as an aliphatic diacid building block for polymer synthesis, serving as a precursor for nylon-type polyamides and polyesters with intermediate chain lengths. It is employed in the production of specialty polymers and copolymers with tailored properties, including high-temperature and chemical resistance. In addition, pimelic acid can be used as a chemical intermediate to prepare functionalized monomers and crosslinkable derivatives for coatings, inks, and adhesives. It also serves as a precursor in organic synthesis for various pharmaceutical and agrochemical intermediates under controlled conditions, and may be evaluated in research and development for advanced materials used in electronics and related fields. All uses are subject to local regulations and formulation limits.
