Description

Compared with other compounds in its class, the molecular weight of 373.39 g/mol gives (2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2,4-difluorophenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2,4-difluorophenyl)methanone (CAS 898756-63-3), molecular formula C21H21F2NO3 and molecular weight 373.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2,4-difluorophenyl)methanone (C21H21F2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 373.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
