Chemical Structure
Description
The molecular framework of Ethyl 5-((7-ethoxy-7-oxoheptyl)-oxy)-4-methoxy-2-nitrobenzoate (C19H27NO8) is characterized by a flavonoid core, an amide 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).
Ethyl 5-((7-ethoxy-7-oxoheptyl)-oxy)-4-methoxy-2-nitrobenzoate (CAS 1012067-92-3) is a high-purity analytical reference standard with the molecular formula C19H27NO8 and a molecular weight of 397.42 g/mol.
