1-(3-Fluorophenyl)-1h-1,2,3-triazole-5-carboxylic acid CAS 1153490-92-6

Description

1-(3-Fluorophenyl)-1h-1,2,3-triazole-5-carboxylic acid (CAS 1153490-92-6), molecular formula C9H6FN3O2 and molecular weight 207.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H6FN3O2, 1-(3-Fluorophenyl)-1h-1,2,3-triazole-5-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 207.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
