Chemical Structure

Acetazolamide EP Impurity G Hydrochloride CAS 59909-21-6 chemical structure

Description

The molecular framework of Acetazolamide EP Impurity G Hydrochloride (C2H3N3S2HCl) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Acetazolamide EP Impurity G Hydrochloride (CAS 59909-21-6) is a high-purity analytical reference standard with the molecular formula C2H3N3S2HCl and a molecular weight of 169.65 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Acetazolamide EP Impurity G Hydrochloride 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.
