Chemical Structure
Description
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.
3-(2-Fluorophenyl)-[1,2,4]triazolo[4,3-a]pyridine-8-carboxylic acid (CAS 1206970-37-7), molecular formula C13H8FN3O2 and molecular weight 257.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H8FN3O2, 3-(2-Fluorophenyl)-[1,2,4]triazolo[4,3-a]pyridine-8-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
