Chemical Structure
Description
Owing to a carbohydrate-derived structure, a sulfone group, fluorine substitution, 2,2,3,3,4,4-Hexafluoro-4-sulfinobutanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.11 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.
2,2,3,3,4,4-Hexafluoro-4-sulfinobutanoic acid (CAS 115432-29-6), molecular formula C4H2F6O4S and molecular weight 260.11 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
