Ubrogepant Impurity 31 CAS CATO-C4X-340231

Description

The occurrence of Ubrogepant Impurity 31 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ubrogepant Impurity 31 (CAS CATO-C4X-340231), a pharmacopoeial impurity reference standard (molecular formula C17H21F3N2O3, MW 358.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H21F3N2O3, Ubrogepant Impurity 31 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 358.36 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).

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.
