Chemical Structure

Atogepant Impurity 90 CAS CATO-C4X-328590 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 834.85 g/mol gives Atogepant Impurity 90 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Atogepant Impurity 90 (CAS CATO-C4X-328590) is a certified pharmaceutical impurity reference standard with the molecular formula C20H26F3NO5C20H26F3NO5 and a molecular weight of 834.85 g/mol.

Structurally, Atogepant Impurity 90 (C20H26F3NO5C20H26F3NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 834.85 g/mol, it falls into the 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.
