Chemical Structure

3,4,5-Trichlorophenylboronic Acid CAS 862248-93-9 chemical structure

Description

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.

3,4,5-Trichlorophenylboronic Acid (CAS 862248-93-9) is a high-purity analytical reference standard with the molecular formula C6H4BCl3O2 and a molecular weight of 225.26 g/mol.

3,4,5-Trichlorophenylboronic Acid (C6H4BCl3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
