Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.62 g/mol gives 5,5-Difluoro-7-oxa-2-azaspiro[3.5]Nonane hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,5-Difluoro-7-oxa-2-azaspiro[3.5]Nonane hydrochloride (CAS 2227206-19-9), molecular formula C7H11F2NOHCl and molecular weight 199.62 g/mol, is a CATO reference standard with documented purity and traceability.
5,5-Difluoro-7-oxa-2-azaspiro[3.5]Nonane hydrochloride (C7H11F2NOHCl) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
