Chemical Structure

2-[(2,3-Dichlorophenyl)methoxy]-2,3-dihydro-1H-isoindole-1,3-dione CAS 321430-36-8 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.

2-[(2,3-Dichlorophenyl)methoxy]-2,3-dihydro-1H-isoindole-1,3-dione (CAS 321430-36-8) is a high-purity analytical reference standard with the molecular formula C15H9Cl2NO3 and a molecular weight of 322.14 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-[(2,3-Dichlorophenyl)methoxy]-2,3-dihydro-1H-isoindole-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
