Bumetanide Impurity 97 CAS 28328-60-1

Description

Compared with other compounds in its class, the molecular weight of 364.42 g/mol gives Bumetanide Impurity 97 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bumetanide Impurity 97 (CAS 28328-60-1), a pharmacopoeial impurity reference standard (molecular formula C17H20N2O5S, MW 364.42 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Bumetanide Impurity 97 (C17H20N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Bumetanide Impurity 97 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.
