Chemical Structure
Description
CATO supplies (4'-Butyl-[1,1'-biphenyl]-4-yl)boronic acid (CAS 145413-17-8), a certified reference material (molecular formula C16H19BO2, MW 254.13 g/mol) for analytical method development and quality control.
Structurally, (4'-Butyl-[1,1'-biphenyl]-4-yl)boronic acid (C16H19BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 254.13 g/mol, it falls into the medium-molecular-weight range. 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).
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.
