Chemical Structure
Description
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.
Flurbiprofen Impurity 100 (CAS CATO-C4X-1444100) is a certified pharmaceutical impurity reference standard with the molecular formula C16H22N2O6 and a molecular weight of 338.36 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Flurbiprofen Impurity 100 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
