Chemical Structure
Description
1-Fluoro-5-iodo-4-methyl-2-nitrobenzene (C7H5FINO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1-Fluoro-5-iodo-4-methyl-2-nitrobenzene (CAS 1779128-45-8), molecular formula C7H5FINO2 and molecular weight 281.02 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
