(3-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-chlorophenyl)methanone CAS 898761-99-4

Description

Compared with other compounds in its class, the molecular weight of 371.86 g/mol gives (3-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-chlorophenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-chlorophenyl)methanone (CAS 898761-99-4), molecular formula C21H22ClNO3 and molecular weight 371.86 g/mol, is a CATO reference standard with documented purity and traceability.

(3-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-chlorophenyl)methanone (C21H22ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
