  • Applications

    Ornithine aspartate (CAS 3230-94-2) is primarily used as an amino acid salt in pharmaceutical formulations and dietary supplement preparations, serving as a source of ornithine and aspartate for product formulations. It is also employed as an intermediate for the synthesis of ornithine/aspartate-containing peptides in chemical research and manufacturing. In the analytical and biochemical context, OA can be used as a reference standard and a matrix for amino acid analysis, and at the development stage it may be regarded as a precursor for synthesizing related pharmaceutical compounds. These applications are subject to local regulations and formulation limits.
