Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-chloro-1-phenyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine 91896-57-0 CP-66713 MFCD17215961 PF-1716311.
CATO supplies 8-chloro-1-phenyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine 91896-57-0 CP-66713 MFCD17215961 PF-1716311 (CAS 91896-57-0), a certified reference material (molecular formula C15H28ClN5, MW 313.87 g/mol) for analytical method development and quality control.
The molecular framework of 8-chloro-1-phenyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine 91896-57-0 CP-66713 MFCD17215961 PF-1716311 (C15H28ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 8-chloro-1-phenyl-[1,2,4]triazolo[4,3-a]quinoxalin-4-amine 91896-57-0 CP-66713 MFCD17215961 PF-1716311 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.
