Chemical Structure

Topiramate Impurity 23 CAS 18549-40-1 chemical structure

Description

The occurrence of Topiramate Impurity 23 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Topiramate Impurity 23 (CAS 18549-40-1) is a certified pharmaceutical impurity reference standard with the molecular formula C9H16O6 and a molecular weight of 220.22 g/mol.

Topiramate Impurity 23 (C9H16O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Topiramate Impurity 23 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.
