Chemical Structure
Description
The molecular framework of 1-(6-(Tritylamino)pyridin-3-yl)ethan-1-one (C26H22N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(6-(Tritylamino)pyridin-3-yl)ethan-1-one (CAS 49647-11-2) is a high-purity analytical reference standard with the molecular formula C26H22N2O and a molecular weight of 378.47 g/mol.
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.
