Chemical Structure
Description
As a certified reference material (CRM), Pioglitazone Impurity 13 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.
Pioglitazone Impurity 13 (CAS CATO-C4X-138313) is a certified pharmaceutical impurity reference standard with the molecular formula C9H12ClNHCl and a molecular weight of 206.11 g/mol.
The molecular framework of Pioglitazone Impurity 13 (C9H12ClNHCl) is characterized by a nitrile group, 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 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.
