Chemical Structure
Description
Structurally, 4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(4-bromophenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one (C28H26BrNO5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 536.41 g/mol, it falls into the moderately-high-molecular-weight range. 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).
4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(4-bromophenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one (CAS 500272-23-1) is a high-purity analytical reference standard with the molecular formula C28H26BrNO5 and a molecular weight of 536.41 g/mol.
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.
