1-(3-Fluorophenyl)-5-(pyridin-2-yl)-1H-1,2,3-triazole-4-carboxylic acid CAS 1326843-80-4

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.

1-(3-Fluorophenyl)-5-(pyridin-2-yl)-1H-1,2,3-triazole-4-carboxylic acid (CAS 1326843-80-4), molecular formula C14H9FN4O2 and molecular weight 284.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(3-Fluorophenyl)-5-(pyridin-2-yl)-1H-1,2,3-triazole-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 1-(3-Fluorophenyl)-5-(pyridin-2-yl)-1H-1,2,3-triazole-4-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.
