Chemical Structure

(5-methyl-1-benzothiophen-2-yl)boronic acid CAS 136099-65-5 chemical structure

Description

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.

CATO supplies (5-methyl-1-benzothiophen-2-yl)boronic acid (CAS 136099-65-5), a certified reference material (molecular formula C9H17BO2S, MW 200.11 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H17BO2S, (5-methyl-1-benzothiophen-2-yl)boronic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 200.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
