Chemical Structure

Indapamide Impurity 52 CAS CATO-C4X-140052 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 271.74 g/mol gives Indapamide Impurity 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Indapamide Impurity 52 (CAS CATO-C4X-140052) is a certified pharmaceutical impurity reference standard with the molecular formula C16H14ClNO and a molecular weight of 271.74 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Indapamide Impurity 52 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 271.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), Indapamide Impurity 52 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.
