Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5,5-Difluoro-1-oxaspiro[2.3]hexane (CAS 1197420-24-8), molecular formula C5H6F2O and molecular weight 120.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, 5,5-Difluoro-1-oxaspiro[2.3]hexane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.10 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.
