Chemical Structure

2-(4-(3,4-Difluorophenyl)thiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1402227-89-7 chemical structure

Description

As a certified reference material (CRM), 2-(4-(3,4-Difluorophenyl)thiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 2-(4-(3,4-Difluorophenyl)thiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1402227-89-7), a certified reference material (molecular formula C16H17BF2O2S, MW 322.18 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 2-(4-(3,4-Difluorophenyl)thiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
