CATO supplies 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-spiro[2H-1-benzopyran-2,4'-piperidine]-1'-carboxylic acid 1,1-dimethylethyl ester (CAS 911228-63-2), a certified reference material (molecular formula C24H34BNO5, MW 427.34 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-spiro[2H-1-benzopyran-2,4'-piperidine]-1'-carboxylic acid 1,1-dimethylethyl ester (C24H34BNO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
