Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4'-Methoxy-[1,1'-biphenyl]-2-carboxylicacid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.24 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).
4'-Methoxy-[1,1'-biphenyl]-2-carboxylicacid (CAS 18110-71-9), molecular formula C14H12O3 and molecular weight 228.24 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
