Chemical Structure
Description
The occurrence of Hydrochlorothiazide-13C6 is closely related to an amide group, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Hydrochlorothiazide-13C6 (CAS 1261396-79-5) is a high-purity analytical reference standard with the molecular formula C[13C]6H8ClN3O4S2 and a molecular weight of 303.70 g/mol.
Hydrochlorothiazide-13C6 (C[13C]6H8ClN3O4S2) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
