Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 583.46 g/mol gives Indapamide Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Indapamide Impurity 29 (CAS CATO-C4X-140029) is a certified pharmaceutical impurity reference standard with the molecular formula C23H20Cl2N4O6S2 and a molecular weight of 583.46 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Indapamide Impurity 29 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 583.46 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.
CATO manufactures Indapamide Impurity 29 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.
