4'-(((Benzyloxy)carbonyl)amino)-[1,1'-biphenyl]-4-carboxylic acid CAS 778601-54-0

Description

4'-(((Benzyloxy)carbonyl)amino)-[1,1'-biphenyl]-4-carboxylic acid (CAS 778601-54-0) is a high-purity analytical reference standard with the molecular formula C21H17NO4 and a molecular weight of 347.36 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4'-(((Benzyloxy)carbonyl)amino)-[1,1'-biphenyl]-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.36 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.
