Bumetanide Impurity 60 CAS CATO-C4X-198660

Description

The occurrence of Bumetanide Impurity 60 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Bumetanide Impurity 60 (CAS CATO-C4X-198660) is a certified pharmaceutical impurity reference standard with the molecular formula C19H22N2O7S and a molecular weight of 422.45 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Bumetanide Impurity 60 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 422.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Bumetanide Impurity 60 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.
