Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2,6-Bis(4-nitrophenyl)pyridin-4-yl)phenol (CAS 850735-06-7) is a high-purity analytical reference standard with the molecular formula C23H15N3O5 and a molecular weight of 413.38 g/mol.
Structurally, 4-(2,6-Bis(4-nitrophenyl)pyridin-4-yl)phenol (C23H15N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 413.38 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).
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.
