Chemical Structure
Description
The occurrence of L-Ornithine L-Aspartate Impurity 1 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
L-Ornithine L-Aspartate Impurity 1 (CAS CATO-C4X-25361) is a certified pharmaceutical impurity reference standard with the molecular formula C9H15N3O4 and a molecular weight of 229.23 g/mol.
L-Ornithine L-Aspartate Impurity 1 (C9H15N3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), L-Ornithine L-Aspartate Impurity 1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
