Chemical Structure
Description
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.
CATO supplies 2-Methyl-4-(4-(2-(4-((2-methyl-1,3-dioxoisoindolin-5-yl)oxy)phenyl)propan-2-yl)phenoxy)isoindoline-1,3-dione (CAS 63227-27-0), a certified reference material (molecular formula C33H26N2O6, MW 546.57 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Methyl-4-(4-(2-(4-((2-methyl-1,3-dioxoisoindolin-5-yl)oxy)phenyl)propan-2-yl)phenoxy)isoindoline-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 546.57 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.
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.
