Chemical Structure
Description
3',4',5'-Trimethoxy-[1,1'-biphenyl]-4-carboxylic acid (C16H16O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
3',4',5'-Trimethoxy-[1,1'-biphenyl]-4-carboxylic acid (CAS 203722-36-5) is a high-purity analytical reference standard with the molecular formula C16H16O5 and a molecular weight of 288.30 g/mol.
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.
