CATO supplies 2-(4,5,6,7-Tetrachloro-1,3-dioxoisoindolin-2-yl)benzoic acid (CAS 351998-35-1), a certified reference material (molecular formula C15H5Cl4NO4, MW 405.02 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4,5,6,7-Tetrachloro-1,3-dioxoisoindolin-2-yl)benzoic acid (C15H5Cl4NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
