Chemical Structure

4-Methyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate CAS 157123-02-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 246.16 g/mol gives 4-Methyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Methyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate (CAS 157123-02-9) is a high-purity analytical reference standard with the molecular formula C6H5F3O5S and a molecular weight of 246.16 g/mol.

Owing to a carbohydrate-derived structure, a sulfone group, fluorine substitution, 4-Methyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.16 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.
