Compared with other compounds in its class, the molecular weight of 626.53 g/mol gives Rivaroxaban Impurity 164 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Rivaroxaban Impurity 164 (CAS 1809279-97-7), a pharmacopoeial impurity reference standard (molecular formula C26H25Cl2N3O7S2, MW 626.53 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Rivaroxaban Impurity 164 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 626.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Rivaroxaban Impurity 164 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.
