1-(Difluoro(phenylsulfonyl)methyl)-3,3-dimethyl-1,3-dihydro-1lambda3-benzo[d][1,2]iodaoxole (CAS 1052174-67-0), molecular formula C16H15F2IO3S and molecular weight 452.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, a polycyclic aromatic system, 1-(Difluoro(phenylsulfonyl)methyl)-3,3-dimethyl-1,3-dihydro-1lambda3-benzo[d][1,2]iodaoxole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
