Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 370.85 g/mol gives Glimepiride Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Glimepiride Impurity 9 (CAS 119043-16-2) is a high-purity analytical reference standard with the molecular formula C16H19ClN2O4S and a molecular weight of 370.85 g/mol.
The molecular framework of Glimepiride Impurity 9 (C16H19ClN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. 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 Glimepiride Impurity 9 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.
