Description
The occurrence of 697-11-0 Hexafluorocyclobutene Cyclobutene, hexafluoro- 4-05-00-00208 (Beilstein Handbook Reference) BRN 2047158 EINECS 211-803-2 1,2,3,3,4,4-Hexafluorocyclobutene Perfluorocyclobutene is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
697-11-0 Hexafluorocyclobutene Cyclobutene, hexafluoro- 4-05-00-00208 (Beilstein Handbook Reference) BRN 2047158 EINECS 211-803-2 1,2,3,3,4,4-Hexafluorocyclobutene Perfluorocyclobutene (CAS 697-11-0), molecular formula C4F6 and molecular weight 162.03 g/mol, is a CATO reference standard with documented purity and traceability.
697-11-0 Hexafluorocyclobutene Cyclobutene, hexafluoro- 4-05-00-00208 (Beilstein Handbook Reference) BRN 2047158 EINECS 211-803-2 1,2,3,3,4,4-Hexafluorocyclobutene Perfluorocyclobutene (C4F6) contains fluorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
