Description

Compared with other compounds in its class, the molecular weight of 666.14 g/mol gives B,B′-[5′′-(4′-Borono[1,1′-biphenyl]-4-yl)[1,1′:4′,1′′:3′′,1′′′:4′′′,1′′′′-quinquephenyl]-4,4′′′′-diyl]bis[boronic acid] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

B,B′-[5′′-(4′-Borono[1,1′-biphenyl]-4-yl)[1,1′:4′,1′′:3′′,1′′′:4′′′,1′′′′-quinquephenyl]-4,4′′′′-diyl]bis[boronic acid] (CAS 1290630-80-6) is a high-purity analytical reference standard with the molecular formula C42H33B3O6 and a molecular weight of 666.14 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, B,B′-[5′′-(4′-Borono[1,1′-biphenyl]-4-yl)[1,1′:4′,1′′:3′′,1′′′:4′′′,1′′′′-quinquephenyl]-4,4′′′′-diyl]bis[boronic acid] is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 666.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
