Chemical Structure
Description
4-Methylthiophene-2-boronic Acid (CAS 162607-15-0) is a high-purity analytical reference standard with the molecular formula C5H7BO2S and a molecular weight of 141.98 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 4-Methylthiophene-2-boronic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
