Chemical Structure
Description
The molecular framework of 4-(Isocyano(tosyl)methyl)-1,2-dimethoxybenzene (C17H17NO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
4-(Isocyano(tosyl)methyl)-1,2-dimethoxybenzene (CAS 71146-67-3) is a high-purity analytical reference standard with the molecular formula C17H17NO4S and a molecular weight of 331.39 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.
