Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 479.61 g/mol gives Cis-Bilastine N-Oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cis-Bilastine N-Oxide (CAS 1934257-94-9) is a high-purity analytical reference standard with the molecular formula C28H37N3O4 and a molecular weight of 479.61 g/mol.
Cis-Bilastine N-Oxide (C28H37N3O4) contains a steroid core, an amide 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. 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 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), Cis-Bilastine N-Oxide 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.
