Chemical Structure
Description
The occurrence of 3-(4-Hydroxyphenyl)-10-nitro-3-azatricyclo[7.3.1.0,5,13]trideca-1(13),5,7,9,11-pentaene-2,4-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 3-(4-Hydroxyphenyl)-10-nitro-3-azatricyclo[7.3.1.0,5,13]trideca-1(13),5,7,9,11-pentaene-2,4-dione (CAS 42388-17-0), a certified reference material (molecular formula C18H10N2O5, MW 334.28 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 3-(4-Hydroxyphenyl)-10-nitro-3-azatricyclo[7.3.1.0,5,13]trideca-1(13),5,7,9,11-pentaene-2,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
