Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 202.18 g/mol gives Acetazolamide EP Impurity D Sodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Acetazolamide EP Impurity D Sodium Salt (CAS 72296-05-0), molecular formula C2H3N4O2S2Na and molecular weight 202.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Acetazolamide EP Impurity D Sodium Salt (C2H3N4O2S2Na) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Acetazolamide EP Impurity D Sodium Salt 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.
