Chemical Structure
Description
The molecular framework of Methyl 4-nitro-3-[(2,4,6-trimethylbenzenesulfonyl)oxy]benzoate (C17H17NO7S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Methyl 4-nitro-3-[(2,4,6-trimethylbenzenesulfonyl)oxy]benzoate (CAS 297150-08-4) is a high-purity analytical reference standard with the molecular formula C17H17NO7S and a molecular weight of 379.38 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.
