(2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(4-bromo-2-fluorophenyl)methanone CAS 898756-36-0 chemical structure

Description

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.

(2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(4-bromo-2-fluorophenyl)methanone (CAS 898756-36-0) is a high-purity analytical reference standard with the molecular formula C21H21BrFNO3 and a molecular weight of 434.30 g/mol.

Based on its molecular formula C21H21BrFNO3, (2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(4-bromo-2-fluorophenyl)methanone contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 434.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
