Chemical Structure
Description
CATO supplies 3-Bromothiophene-2-boronic acid (CAS 162607-26-3), a certified reference material (molecular formula C4H8BBrO2S, MW 210.89 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 3-Bromothiophene-2-boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
