(((1-Methyl-4-oxopiperidine-3,5-diylidene)bis(methaneylylidene))bis(4,1-phenylene))diboronic acid (CAS 856849-35-9) is a high-purity analytical reference standard with the molecular formula C20H21B2NO5 and a molecular weight of 377.01 g/mol.
Based on its molecular formula C20H21B2NO5, (((1-Methyl-4-oxopiperidine-3,5-diylidene)bis(methaneylylidene))bis(4,1-phenylene))diboronic acid contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 377.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
