Chemical Structure

(E)-4,4,5,5-Tetramethyl-2-(3-(trifluoromethyl)styryl)-1,3,2-dioxaborolane CAS 1073354-88-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4,4,5,5-Tetramethyl-2-(3-(trifluoromethyl)styryl)-1,3,2-dioxaborolane.

CATO supplies (E)-4,4,5,5-Tetramethyl-2-(3-(trifluoromethyl)styryl)-1,3,2-dioxaborolane (CAS 1073354-88-7), a certified reference material (molecular formula C15H18BF3O2, MW 298.11 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (E)-4,4,5,5-Tetramethyl-2-(3-(trifluoromethyl)styryl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.11 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.

As a certified reference material (CRM), (E)-4,4,5,5-Tetramethyl-2-(3-(trifluoromethyl)styryl)-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.
