Chemical Structure
Description
(5-(tert-Butyl)thiophen-2-yl)boronic acid (CAS 495382-48-4), molecular formula C8H13BO2S and molecular weight 184.06 g/mol, is a CATO reference standard with documented purity and traceability.
(5-(tert-Butyl)thiophen-2-yl)boronic acid (C8H13BO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
