Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1059.20 g/mol gives Relugolix Impurity 28 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Relugolix Impurity 28 (CAS CATO-C4X-242928) is a certified pharmaceutical impurity reference standard with the molecular formula C54H58F4N6O8S2 and a molecular weight of 1059.20 g/mol.
Structurally, Relugolix Impurity 28 (C54H58F4N6O8S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 1059.20 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.
CATO manufactures Relugolix Impurity 28 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
