Chemical Structure
Description
As a certified reference material (CRM), Hydrochlorothiazide Impurity 53 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.
Hydrochlorothiazide Impurity 53 (CAS CATO-C4X-117753) is a high-purity analytical reference standard with the molecular formula C6H7ClN2O5S2HCl and a molecular weight of 323.16 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution, Hydrochlorothiazide Impurity 53 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
