Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 452.49 g/mol gives Diflorasone impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diflorasone impurity 4 (CAS CATO-C4X-24804) is a certified pharmaceutical impurity reference standard with the molecular formula C24H30F2O6 and a molecular weight of 452.49 g/mol.
Structurally, Diflorasone impurity 4 (C24H30F2O6) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 452.49 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
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.
