Description

The occurrence of 356-18-3 1,2-Dichloro-1,2,3,3,4,4-hexafluorocyclobutane Cyclobutane, 1,2-dichlorohexafluoro- Cyclobutane, 1,2-dichloro-1,2,3,3,4,4-hexafluoro- (9CI) 1,2-Dichlorohexafluorocyclobutane Cyclobutane, 1,2-dichloro-1,2,3,3,4,4-hexafluoro- BRN 1909267 1,2-Dichloroperfluorocyclobutane EINECS 206-599-7 is closely related to fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

356-18-3 1,2-Dichloro-1,2,3,3,4,4-hexafluorocyclobutane Cyclobutane, 1,2-dichlorohexafluoro- Cyclobutane, 1,2-dichloro-1,2,3,3,4,4-hexafluoro- (9CI) 1,2-Dichlorohexafluorocyclobutane Cyclobutane, 1,2-dichloro-1,2,3,3,4,4-hexafluoro- BRN 1909267 1,2-Dichloroperfluorocyclobutane EINECS 206-599-7 (CAS 356-18-3) is a high-purity analytical reference standard with the molecular formula C4Cl2F6 and a molecular weight of 232.94 g/mol.

The molecular framework of 356-18-3 1,2-Dichloro-1,2,3,3,4,4-hexafluorocyclobutane Cyclobutane, 1,2-dichlorohexafluoro- Cyclobutane, 1,2-dichloro-1,2,3,3,4,4-hexafluoro- (9CI) 1,2-Dichlorohexafluorocyclobutane Cyclobutane, 1,2-dichloro-1,2,3,3,4,4-hexafluoro- BRN 1909267 1,2-Dichloroperfluorocyclobutane EINECS 206-599-7 (C4Cl2F6) is characterized by fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
