3-Methyl-4-nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxylic acid CAS 89239-84-9

Description

3-Methyl-4-nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxylic acid (CAS 89239-84-9), molecular formula C7H6F3N3O4 and molecular weight 253.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H6F3N3O4, 3-Methyl-4-nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxylic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.14 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.
