Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 380.44 g/mol gives 2,6-Dicyclohexylpyrrolo[3,4-f]isoindole-1,3,5,7(2H,6H)-tetraone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,6-Dicyclohexylpyrrolo[3,4-f]isoindole-1,3,5,7(2H,6H)-tetraone (CAS 31663-85-1), a certified reference material (molecular formula C22H24N2O4, MW 380.44 g/mol) for analytical method development and quality control.
The molecular framework of 2,6-Dicyclohexylpyrrolo[3,4-f]isoindole-1,3,5,7(2H,6H)-tetraone (C22H24N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
