Chemical Structure
Description
CATO supplies 4'-Borono-[1,1'-biphenyl]-4-carboxylic acid (CAS 872341-95-2), a certified reference material (molecular formula C13H11BO4, MW 242.04 g/mol) for analytical method development and quality control.
4'-Borono-[1,1'-biphenyl]-4-carboxylic acid (C13H11BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
