Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Flurbiprofen EP Impurity A(Flurbiprofen Related Compound A).
Flurbiprofen EP Impurity A(Flurbiprofen Related Compound A) (CAS 6341-72-6) is a certified pharmaceutical impurity reference standard with the molecular formula C15H14O2 and a molecular weight of 226.27 g/mol.
Based on its molecular formula C15H14O2, Flurbiprofen EP Impurity A(Flurbiprofen Related Compound A) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.27 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).
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), Flurbiprofen EP Impurity A(Flurbiprofen Related Compound A) 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.
