Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 340.29 g/mol gives Apremilast impurity 94 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Apremilast impurity 94 (CAS CATO-C4X-100994) is a certified pharmaceutical impurity reference standard with the molecular formula C17H12N2O6 and a molecular weight of 340.29 g/mol.
Based on its molecular formula C17H12N2O6, Apremilast impurity 94 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures Apremilast impurity 94 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
