Chemical Structure
Description
1-(3-(1h-Imidazol-1-yl)propyl)-4-benzoyl-3-hydroxy-5-(p-tolyl)-1,5-dihydro-2h-pyrrol-2-one (CAS 309270-92-6) is a high-purity analytical reference standard with the molecular formula C24H23N3O3 and a molecular weight of 401.46 g/mol.
1-(3-(1h-Imidazol-1-yl)propyl)-4-benzoyl-3-hydroxy-5-(p-tolyl)-1,5-dihydro-2h-pyrrol-2-one (C24H23N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
