Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 309.27 g/mol gives Dopamine Impurity 48 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dopamine Impurity 48 (CAS CATO-C4X-190848) is a certified pharmaceutical impurity reference standard with the molecular formula C14H15NO7 and a molecular weight of 309.27 g/mol.
Dopamine Impurity 48 (C14H15NO7) contains a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Dopamine Impurity 48 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.
