Chemical Structure
Description
1-(1H-Imidazol-1-yl)-2-(3-methoxybenzyl)-3,3-dimethylbutan-1-one (CAS 89372-61-2), molecular formula C17H22N2O2 and molecular weight 286.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(1H-Imidazol-1-yl)-2-(3-methoxybenzyl)-3,3-dimethylbutan-1-one (C17H22N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 286.37 g/mol, it falls into the medium-molecular-weight range. 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.
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.
