Chemical Structure

4-(tert-Butyl)phenyl trifluoromethanesulfonate CAS 154318-75-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 282.28 g/mol gives 4-(tert-Butyl)phenyl trifluoromethanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(tert-Butyl)phenyl trifluoromethanesulfonate (CAS 154318-75-9), a certified reference material (molecular formula C11H13F3O3S, MW 282.28 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, an aromatic ring system, 4-(tert-Butyl)phenyl trifluoromethanesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.28 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.

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.
