2-(2-Nitrobenzylidene)-1H-indene-1,3(2H)-dione CAS 15875-61-3 chemical structure

Description

The occurrence of 2-(2-Nitrobenzylidene)-1H-indene-1,3(2H)-dione 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.

CATO supplies 2-(2-Nitrobenzylidene)-1H-indene-1,3(2H)-dione (CAS 15875-61-3), a certified reference material (molecular formula C16H9NO4, MW 279.25 g/mol) for analytical method development and quality control.

2-(2-Nitrobenzylidene)-1H-indene-1,3(2H)-dione (C16H9NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
