Chemical Structure

Bisoprolol Impurity 92 CAS CATO-C4X-124792 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 339.43 g/mol gives Bisoprolol Impurity 92 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bisoprolol Impurity 92 (CAS CATO-C4X-124792) is a certified pharmaceutical impurity reference standard with the molecular formula C18H29NO5 and a molecular weight of 339.43 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Bisoprolol Impurity 92 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Bisoprolol Impurity 92 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.
