Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 664.73 g/mol gives Bromfenac Impurity 61 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bromfenac Impurity 61 (CAS CATO-C4X-200261) is a certified pharmaceutical impurity reference standard with the molecular formula C30H17Br2ClN2O4 and a molecular weight of 664.73 g/mol.
Based on its molecular formula C30H17Br2ClN2O4, Bromfenac Impurity 61 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 664.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Bromfenac Impurity 61 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.
