Chemical Structure
Description
CATO supplies Ytterbium fluoride oxide, 99.99% (REO) (CAS 15587-02-7), a certified reference material (molecular formula FOYb, MW 208.04 g/mol) for analytical method development and quality control.
Ytterbium fluoride oxide, 99.99% (REO) (FOYb) contains fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
