Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(3-bromophenyl)-3-hydroxy-1-(3-methoxypropyl)-1H-pyrrol-2(5H)-one.
4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(3-bromophenyl)-3-hydroxy-1-(3-methoxypropyl)-1H-pyrrol-2(5H)-one (CAS 500146-47-4) is a high-purity analytical reference standard with the molecular formula C29H28BrNO5 and a molecular weight of 550.44 g/mol.
The molecular framework of 4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(3-bromophenyl)-3-hydroxy-1-(3-methoxypropyl)-1H-pyrrol-2(5H)-one (C29H28BrNO5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
