2-(trifluoromethyl)-5H,6H,7H,8H-imidazo[1,2-a]pyridine-3-carboxylic acid (CAS 1781636-40-5), molecular formula C9H9F3N2O2 and molecular weight 234.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(trifluoromethyl)-5H,6H,7H,8H-imidazo[1,2-a]pyridine-3-carboxylic acid (C9H9F3N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-(trifluoromethyl)-5H,6H,7H,8H-imidazo[1,2-a]pyridine-3-carboxylic acid 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.
