(2S,3S)-1,1,1,4,4,4-hexafluorobutane-2,3-diol CAS 119209-24-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,3S)-1,1,1,4,4,4-hexafluorobutane-2,3-diol.

(2S,3S)-1,1,1,4,4,4-hexafluorobutane-2,3-diol (CAS 119209-24-4), molecular formula C4H4F6O2 and molecular weight 198.06 g/mol, is a CATO reference standard with documented purity and traceability.

(2S,3S)-1,1,1,4,4,4-hexafluorobutane-2,3-diol (C4H4F6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
