Chemical Structure

2,2'-(5-Chloro-4,5-dihydrothiophene-2,4-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) CAS 942070-16-8 chemical structure

Description

CATO supplies 2,2'-(5-Chloro-4,5-dihydrothiophene-2,4-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (CAS 942070-16-8), a certified reference material (molecular formula C16H27B2ClO4S, MW 372.52 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2,2'-(5-Chloro-4,5-dihydrothiophene-2,4-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
