4,4,5,5-tetramethyl-2-[(E)-2-(thiophen-2-yl)ethenyl]-1,3,2-dioxaborolane CAS 161395-82-0

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 4,4,5,5-tetramethyl-2-[(E)-2-(thiophen-2-yl)ethenyl]-1,3,2-dioxaborolane (CAS 161395-82-0), a certified reference material (molecular formula C12H21BO2S, MW 240.17 g/mol) for analytical method development and quality control.

The molecular framework of 4,4,5,5-tetramethyl-2-[(E)-2-(thiophen-2-yl)ethenyl]-1,3,2-dioxaborolane (C12H21BO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 4,4,5,5-tetramethyl-2-[(E)-2-(thiophen-2-yl)ethenyl]-1,3,2-dioxaborolane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
