Mirtazapine EP Impurity A (CAS 155172-12-6) is a certified pharmaceutical impurity reference standard with the molecular formula C17H19N3O and a molecular weight of 281.35 g/mol.
Mirtazapine EP Impurity A (C17H19N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
