Chemical Structure
Description
The occurrence of 2-((5-Nitrofuran-2-yl)methylene)-1,3-dioxo-2,3-dihydro-1H-indene-5-carboxylic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((5-Nitrofuran-2-yl)methylene)-1,3-dioxo-2,3-dihydro-1H-indene-5-carboxylic acid (CAS 451461-46-4), molecular formula C15H7NO7 and molecular weight 313.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((5-Nitrofuran-2-yl)methylene)-1,3-dioxo-2,3-dihydro-1H-indene-5-carboxylic acid (C15H7NO7) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
