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 129.
Bumetanide Impurity 129 (CAS CATO-C4X-1986129) is a certified pharmaceutical impurity reference standard with the molecular formula C18H22N2O5S and a molecular weight of 378.44 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Bumetanide Impurity 129 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 378.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Bumetanide Impurity 129 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.
