Chemical Structure

(7-methoxybenzothiophen-2-yl)boronic acid CAS 193965-35-4 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.

(7-methoxybenzothiophen-2-yl)boronic acid (CAS 193965-35-4) is a high-purity analytical reference standard with the molecular formula C9H17BO3S and a molecular weight of 216.11 g/mol.

(7-methoxybenzothiophen-2-yl)boronic acid (C9H17BO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
