Description
7783-95-1 372MAR8LH9 Silver difluoride Silver fluoride (AgF2) Silver (II) fluoride Silver(II) fluoride Argent fluorure [French] Argentic fluoride EINECS 232-037-5 Argent fluorure UNII-372MAR8LH9 (CAS 7783-95-1), molecular formula AgF2 and molecular weight 145.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7783-95-1 372MAR8LH9 Silver difluoride Silver fluoride (AgF2) Silver (II) fluoride Silver(II) fluoride Argent fluorure [French] Argentic fluoride EINECS 232-037-5 Argent fluorure UNII-372MAR8LH9 (AgF2) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
