  • Applications

    9-Oxodecanoic acid (CAS 1422-26-0) is primarily used as an organic synthesis intermediate in industrial manufacturing, enabling formation of beta-keto esters and related carbonyl derivatives. It also serves as a building block in polymers and coatings, where it can act as a monomer, co-monomer, or chain-extender for specialty polyesters and resins. In pharmaceutical and agrochemical development, it is evaluated as a precursor for various intermediates; and in specialty chemicals it may be accessed via acylation and condensation to reach more complex molecules. Its use is subject to local regulations and formulation limits.
