3-Oxoisoindoline-4-carbonitrile CAS 129221-89-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Oxoisoindoline-4-carbonitrile.

CATO supplies 3-Oxoisoindoline-4-carbonitrile (CAS 129221-89-2), a certified reference material (molecular formula C9H6N2O, MW 158.16 g/mol) for analytical method development and quality control.

3-Oxoisoindoline-4-carbonitrile (C9H6N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
