Chemical Structure

Torasemide Impurity 46 CAS CATO-C4X-183646 chemical structure

Description

The occurrence of Torasemide Impurity 46 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.

Torasemide Impurity 46 (CAS CATO-C4X-183646) is a certified pharmaceutical impurity reference standard with the molecular formula C16H19N5O4S and a molecular weight of 377.42 g/mol.

Based on its molecular formula C16H19N5O4S, Torasemide Impurity 46 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 377.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), Torasemide Impurity 46 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.
