Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 507.51 g/mol gives Relugolix Impurity 108 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Relugolix Impurity 108 (CAS CATO-C4X-2429108) is a certified pharmaceutical impurity reference standard with the molecular formula C25H19F2N5O3S and a molecular weight of 507.51 g/mol.
Based on its molecular formula C25H19F2N5O3S, Relugolix Impurity 108 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 507.51 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.
