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-(Difluoromethoxy)-2-iodobenzoic acid (CAS 2383082-26-4), molecular formula C8H5F2IO3 and molecular weight 314.02 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H5F2IO3, 3-(Difluoromethoxy)-2-iodobenzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 314.02 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.
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.
