2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl 4-methylbenzenesulfonate CAS 424-16-8 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.

2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl 4-methylbenzenesulfonate (CAS 424-16-8), molecular formula C14H10F12O3S and molecular weight 486.27 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, an aromatic ring system, 2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 486.27 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.

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.
