4,4,5,5-Tetramethyl-2-(2-(trifluoromethyl)thiophen-3-yl)-1,3,2-dioxaborolane CAS 2246611-07-2

Description

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

4,4,5,5-Tetramethyl-2-(2-(trifluoromethyl)thiophen-3-yl)-1,3,2-dioxaborolane (CAS 2246611-07-2), molecular formula C11H14BF3O2S and molecular weight 278.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 4,4,5,5-Tetramethyl-2-(2-(trifluoromethyl)thiophen-3-yl)-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
