Bumetanide Impurity 57 CAS CATO-C4X-198657 chemical structure

Description

CATO manufactures Bumetanide Impurity 57 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Bumetanide Impurity 57 (CAS CATO-C4X-198657) is a certified pharmaceutical impurity reference standard with the molecular formula C17H19NO4 and a molecular weight of 301.34 g/mol.

Bumetanide Impurity 57 (C17H19NO4) contains a flavonoid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
