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-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4,7-dimethoxyisoindoline-1,3-dione (CAS 160291-60-1), a certified reference material (molecular formula C16H14N2O6, MW 330.29 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4,7-dimethoxyisoindoline-1,3-dione (C16H14N2O6) 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. 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.
