Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.14 g/mol gives Opicapone impurity 28 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Opicapone impurity 28 (CAS CATO-C4X-240428) is a certified pharmaceutical impurity reference standard with the molecular formula C8H6N2O8 and a molecular weight of 258.14 g/mol.
Based on its molecular formula C8H6N2O8, Opicapone impurity 28 contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Opicapone impurity 28 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.
