Description

CATO supplies Tetrafluorohydroquinone tetrafluoro-1,4-hydroquinone 1,2,4,5-tetrafluoro-3,6-dihydroxybenzene 2,3,5,6-tetrafluorohydroquinone tetrafluorobenzene-1,4-diol 1,4-dihydroxytetrafluorobenzene 1,4-dihydroxy-2,3,5,6-tetrafluorobenzene 771-63-1 (CAS 771-63-1), a certified reference material (molecular formula C6H8F4O2, MW 188.12 g/mol) for analytical method development and quality control.

Structurally, Tetrafluorohydroquinone tetrafluoro-1,4-hydroquinone 1,2,4,5-tetrafluoro-3,6-dihydroxybenzene 2,3,5,6-tetrafluorohydroquinone tetrafluorobenzene-1,4-diol 1,4-dihydroxytetrafluorobenzene 1,4-dihydroxy-2,3,5,6-tetrafluorobenzene 771-63-1 (C6H8F4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 188.12 g/mol, it falls into the medium-molecular-weight range. 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.
