Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(Difluoromethyl)-5-fluoro-2-iodo-3-methoxypyridine (CAS 1806879-84-4) is a high-purity analytical reference standard with the molecular formula C7H5F3INO and a molecular weight of 303.02 g/mol.
4-(Difluoromethyl)-5-fluoro-2-iodo-3-methoxypyridine (C7H5F3INO) contains an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
