Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(4-Methylbenzoyl)-9b-phenyl-1H,2H,3H,5H,9bH-imidazo[2,1-a]isoindol-5-one (CAS 338414-88-3), a certified reference material (molecular formula C24H20N2O2, MW 368.43 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-(4-Methylbenzoyl)-9b-phenyl-1H,2H,3H,5H,9bH-imidazo[2,1-a]isoindol-5-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
