Chemical Structure

8-Benzyl-2-methyl-4-phenyl-2,8-diazaspiro[4.5]decan-3-one CAS 79139-56-3 chemical structure

Description

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.

8-Benzyl-2-methyl-4-phenyl-2,8-diazaspiro[4.5]decan-3-one (CAS 79139-56-3) is a high-purity analytical reference standard with the molecular formula C22H26N2O and a molecular weight of 334.45 g/mol.

8-Benzyl-2-methyl-4-phenyl-2,8-diazaspiro[4.5]decan-3-one (C22H26N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
