(4-(Difluoromethyl)-2-fluoro-5-iodopyridin-3-yl)methanol (CAS 1807134-40-2), molecular formula C7H5F3INO and molecular weight 303.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-(Difluoromethyl)-2-fluoro-5-iodopyridin-3-yl)methanol (C7H5F3INO) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
