Chemical Structure
Description
As a certified reference material (CRM), Opicapone Impurity 11 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 Opicapone Impurity 11 (CAS CATO-C4X-240411), a pharmacopoeial impurity reference standard (molecular formula C15H10Cl2N4O6, MW 413.17 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Opicapone Impurity 11 (C15H10Cl2N4O6) is characterized by a flavonoid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
