The occurrence of 4-(2,5-Diphenyl-1h-pyrrol-1-yl)phenol is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(2,5-Diphenyl-1h-pyrrol-1-yl)phenol (CAS 853-38-3) is a high-purity analytical reference standard with the molecular formula C22H17NO and a molecular weight of 311.38 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(2,5-Diphenyl-1h-pyrrol-1-yl)phenol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.38 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).
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.
