Chemical Structure

4-(4-(Benzyloxy)-2-methylbenzoyl)-1-(2-(dimethylamino)ethyl)-3-hydroxy-5-(pyridin-4-yl)-1H-pyrrol-2(5H)-one CAS 488716-22-9 chemical structure

Description

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.

4-(4-(Benzyloxy)-2-methylbenzoyl)-1-(2-(dimethylamino)ethyl)-3-hydroxy-5-(pyridin-4-yl)-1H-pyrrol-2(5H)-one (CAS 488716-22-9) is a high-purity analytical reference standard with the molecular formula C28H29N3O4 and a molecular weight of 471.55 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-(Benzyloxy)-2-methylbenzoyl)-1-(2-(dimethylamino)ethyl)-3-hydroxy-5-(pyridin-4-yl)-1H-pyrrol-2(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 471.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
