Rivaroxaban Impurity 21 CAS 59337-89-2

Description

Compared with other compounds in its class, the molecular weight of 162.59 g/mol gives Rivaroxaban Impurity 21 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Rivaroxaban Impurity 21 (CAS 59337-89-2), a pharmacopoeial impurity reference standard (molecular formula C5H3ClO2S, MW 162.59 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Rivaroxaban Impurity 21 (C5H3ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 162.59 g/mol, it falls into the medium-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 Rivaroxaban Impurity 21 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.
