Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.20 g/mol gives Formoterol Impurity 102 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Formoterol Impurity 102 (CAS 1823724-70-4) is a certified pharmaceutical impurity reference standard with the molecular formula C15H16BrNO2 and a molecular weight of 322.20 g/mol.
Based on its molecular formula C15H16BrNO2, Formoterol Impurity 102 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.20 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.
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), Formoterol Impurity 102 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.
