Chemical Structure

tert-Butyl 4,4-difluoro-5-(((trifluoromethyl)sulfonyl)oxy)pentanoate CAS 1782101-26-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 342.28 g/mol gives tert-Butyl 4,4-difluoro-5-(((trifluoromethyl)sulfonyl)oxy)pentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies tert-Butyl 4,4-difluoro-5-(((trifluoromethyl)sulfonyl)oxy)pentanoate (CAS 1782101-26-1), a certified reference material (molecular formula C10H15F5O5S, MW 342.28 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, tert-Butyl 4,4-difluoro-5-(((trifluoromethyl)sulfonyl)oxy)pentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
