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.
Relugolix Impurity 112 (CAS 1589503-94-5) is a certified pharmaceutical impurity reference standard with the molecular formula C29H28F2N6O6S and a molecular weight of 626.63 g/mol.
Relugolix Impurity 112 (C29H28F2N6O6S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
