Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 318.70 g/mol gives Chlorothiazide Sodium - API Standards distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Chlorothiazide Sodium - API Standards (CAS 7085-44-1) is a high-purity analytical reference standard with the molecular formula C7H6ClN3O4S2Na and a molecular weight of 318.70 g/mol.
Based on its molecular formula C7H6ClN3O4S2Na, Chlorothiazide Sodium - API Standards contains a salt form, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
