4-(1,3-Dioxoisoindolin-2-yl)benzenesulfonic acid CAS 86581-47-7

Description

The occurrence of 4-(1,3-Dioxoisoindolin-2-yl)benzenesulfonic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(1,3-Dioxoisoindolin-2-yl)benzenesulfonic acid (CAS 86581-47-7) is a high-purity analytical reference standard with the molecular formula C14H9NO5S and a molecular weight of 303.29 g/mol.

4-(1,3-Dioxoisoindolin-2-yl)benzenesulfonic acid (C14H9NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
