5-Chloro-1-(4-chlorobenzyl)indoline-2,3-dione CAS 87423-59-4

Description

5-Chloro-1-(4-chlorobenzyl)indoline-2,3-dione (CAS 87423-59-4) is a high-purity analytical reference standard with the molecular formula C15H9Cl2NO2 and a molecular weight of 306.14 g/mol.

5-Chloro-1-(4-chlorobenzyl)indoline-2,3-dione (C15H9Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
