Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-(Allyloxy)benzoyl)-5-(4-(tert-butyl)phenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one.
CATO supplies 4-(4-(Allyloxy)benzoyl)-5-(4-(tert-butyl)phenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one (CAS 618074-25-2), a certified reference material (molecular formula C27H31NO5, MW 449.54 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-(Allyloxy)benzoyl)-5-(4-(tert-butyl)phenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.54 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).
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.
