(S)-2-(5,6-Dichloro-1,3-dioxoisoindolin-2-yl)propanoic acid CAS 111104-26-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 288.08 g/mol gives (S)-2-(5,6-Dichloro-1,3-dioxoisoindolin-2-yl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-2-(5,6-Dichloro-1,3-dioxoisoindolin-2-yl)propanoic acid (CAS 111104-26-8), a certified reference material (molecular formula C11H7Cl2NO4, MW 288.08 g/mol) for analytical method development and quality control.

(S)-2-(5,6-Dichloro-1,3-dioxoisoindolin-2-yl)propanoic acid (C11H7Cl2NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
