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-Hydroxy-2'-methyl-[1,1'-biphenyl]-3-carboxylic acid (CAS 25205-15-6) is a high-purity analytical reference standard with the molecular formula C14H12O3 and a molecular weight of 228.24 g/mol.
Based on its molecular formula C14H12O3, 4-Hydroxy-2'-methyl-[1,1'-biphenyl]-3-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
