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.
N-{2-[2-(tert-Butyl)phenoxy]ethyl}-2-isopropoxyaniline (CAS 1040683-70-2) is a high-purity analytical reference standard with the molecular formula C21H29NO2 and a molecular weight of 327.46 g/mol.
Based on its molecular formula C21H29NO2, N-{2-[2-(tert-Butyl)phenoxy]ethyl}-2-isopropoxyaniline contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 327.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
