Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,4-Difluoro-2-((4-iodo-2-methylphenyl)amino)benzoic acid (CAS 934664-21-8), molecular formula C14H10F2INO2 and molecular weight 389.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H10F2INO2, 3,4-Difluoro-2-((4-iodo-2-methylphenyl)amino)benzoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 389.14 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).
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.
