Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 293.84 g/mol gives 盐酸奎斯诺杂质3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 盐酸奎斯诺杂质3 (CAS CATO-C4X-34213), a pharmacopoeial impurity reference standard (molecular formula C16H23N3HCl, MW 293.84 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of 盐酸奎斯诺杂质3 (C16H23N3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 盐酸奎斯诺杂质3 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.
