Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bumetanide Impurity 86.
CATO supplies Bumetanide Impurity 86 (CAS CATO-C4X-198686), a pharmacopoeial impurity reference standard (molecular formula C17H19NO5S, MW 349.40 g/mol) used for the identification and quantification of trace impurities in APIs.
Bumetanide Impurity 86 (C17H19NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 86 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.
