(2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-(methylthio)phenyl)methanone CAS 898755-94-7 chemical structure

Description

The occurrence of (2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-(methylthio)phenyl)methanone is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-(methylthio)phenyl)methanone (CAS 898755-94-7) is a high-purity analytical reference standard with the molecular formula C22H25NO3S and a molecular weight of 383.50 g/mol.

(2-((1,4-Dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)(2-(methylthio)phenyl)methanone (C22H25NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
