Chemical Structure

Bumetanide Impurity 23 CAS CATO-C4X-198623 chemical structure

Description

The occurrence of Bumetanide Impurity 23 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.

CATO supplies Bumetanide Impurity 23 (CAS CATO-C4X-198623), a pharmacopoeial impurity reference standard (molecular formula C25H36N2O5S, MW 476.63 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C25H36N2O5S, Bumetanide Impurity 23 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 476.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Bumetanide Impurity 23 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.
