Chemical Structure
Description
The molecular framework of {5-[(2,2-Dimethylpropoxy)sulfonyl]pyridin-3-yl}boronic acid (C10H16BNO5S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
{5-[(2,2-Dimethylpropoxy)sulfonyl]pyridin-3-yl}boronic acid (CAS 2377606-77-2), molecular formula C10H16BNO5S and molecular weight 273.11 g/mol, is a CATO reference standard with documented purity and traceability.
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.
