Methyl 2-([1,1'-biphenyl]-4-yl)-2-oxoacetate (CAS 16738-11-7) is a high-purity analytical reference standard with the molecular formula C15H12O3 and a molecular weight of 240.25 g/mol.
Structurally, Methyl 2-([1,1'-biphenyl]-4-yl)-2-oxoacetate (C15H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 240.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
