Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Fluoro-1-iodo-3-methoxy-5-(trifluoromethyl)benzene (CAS 2090774-74-4), molecular formula C8H5F4IO and molecular weight 320.02 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-1-iodo-3-methoxy-5-(trifluoromethyl)benzene (C8H5F4IO) contains a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
