Chemical Structure
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 Trimethyl((3-(trifluoromethyl)phenyl)ethynyl)silane (CAS 40230-93-1), a certified reference material (molecular formula C12H13F3Si, MW 242.31 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, an aromatic ring system, Trimethyl((3-(trifluoromethyl)phenyl)ethynyl)silane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.31 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).
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.
