Chemical Structure
Description
As a certified reference material (CRM), Glycopyrronium Bromide Impurity 6 Iodide 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.
CATO supplies Glycopyrronium Bromide Impurity 6 Iodide (CAS CATO-C4X-18176), a pharmacopoeial impurity reference standard (molecular formula C19H27ClNO3I, MW 479.78 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Glycopyrronium Bromide Impurity 6 Iodide (C19H27ClNO3I) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
