Relugolix Impurity N1 CAS 1801551-07-4

Description

Compared with other compounds in its class, the molecular weight of 609.60 g/mol gives Relugolix Impurity N1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Relugolix Impurity N1 (CAS 1801551-07-4), a pharmacopoeial impurity reference standard (molecular formula C28H25F2N7O5S, MW 609.60 g/mol) used for the identification and quantification of trace impurities in APIs.

Relugolix Impurity N1 (C28H25F2N7O5S) 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. 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.
