Description
Compared with other compounds in its class, the molecular weight of 177.22 g/mol gives Rivaroxaban Impurity 53 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rivaroxaban Impurity 53 (CAS 66357-41-3) is a high-purity analytical reference standard with the molecular formula C5H11N3O2S and a molecular weight of 177.22 g/mol.
Rivaroxaban Impurity 53 (C5H11N3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Rivaroxaban Impurity 53 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
