Chemical Structure
Description
The molecular framework of N-(3-bromo-2,6-dimethoxybenzoyl)-N'-(2,3,4,5,6-pentafluorophenyl)urea (C16H10BrF5N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N-(3-bromo-2,6-dimethoxybenzoyl)-N'-(2,3,4,5,6-pentafluorophenyl)urea (CAS 222540-13-8) is a high-purity analytical reference standard with the molecular formula C16H10BrF5N2O4 and a molecular weight of 469.16 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
