[2-(Methoxycarbonyl)thiophen-3-yl]boronic acid CAS 1596339-08-0

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.

CATO supplies [2-(Methoxycarbonyl)thiophen-3-yl]boronic acid (CAS 1596339-08-0), a certified reference material (molecular formula C6H7BO4S, MW 185.99 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, [2-(Methoxycarbonyl)thiophen-3-yl]boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
