Compared with other compounds in its class, the molecular weight of 550.22 g/mol gives Aprocitentan-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Aprocitentan-d4 (CAS CATO-C4X-335510), molecular formula C16H10D4Br2N6O4S and molecular weight 550.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, Aprocitentan-d4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 550.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
