5-Ethyl-1-(4-fluoro-3-methylphenyl)-1H-1,2,3-triazole-4-carboxylic acid CAS 1239720-61-6

Description

CATO supplies 5-Ethyl-1-(4-fluoro-3-methylphenyl)-1H-1,2,3-triazole-4-carboxylic acid (CAS 1239720-61-6), a certified reference material (molecular formula C12H12FN3O2, MW 249.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H12FN3O2, 5-Ethyl-1-(4-fluoro-3-methylphenyl)-1H-1,2,3-triazole-4-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 249.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
