Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Phenyl-1,2,3-oxadiazol-3-ium-5-olate.
CATO supplies 3-Phenyl-1,2,3-oxadiazol-3-ium-5-olate (CAS 120-06-9), a certified reference material (molecular formula C8H6N2O2, MW 162.15 g/mol) for analytical method development and quality control.
The molecular framework of 3-Phenyl-1,2,3-oxadiazol-3-ium-5-olate (C8H6N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
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), 3-Phenyl-1,2,3-oxadiazol-3-ium-5-olate 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.
