2-(2-Chloroethyl)-1H-isoindole-1,3-dione CAS 6270-06-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Chloroethyl)-1H-isoindole-1,3-dione.

2-(2-Chloroethyl)-1H-isoindole-1,3-dione (CAS 6270-06-0), molecular formula C10H8ClNO2 and molecular weight 209.63 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2-Chloroethyl)-1H-isoindole-1,3-dione (C10H8ClNO2) 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.
