Chemical Structure
Description
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.
CATO supplies 2-(2,6-Dimethylphenyl)-1,3-dioxoisoindoline-5-carboxylic acid (CAS 110768-27-9), a certified reference material (molecular formula C17H13NO4, MW 295.29 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2,6-Dimethylphenyl)-1,3-dioxoisoindoline-5-carboxylic acid (C17H13NO4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
