Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-((5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)methyl)furan-2-carboxylic acid (CAS 381184-74-3), molecular formula C11H9F3N2O3 and molecular weight 274.20 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H9F3N2O3, 5-((5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)methyl)furan-2-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 274.20 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.
