Chemical Structure
Description
4,5,7,8,12,13,15,16-Octafluoro[2.2]paracyclophane (CAS 1785-64-4) is a high-purity analytical reference standard with the molecular formula C16H8F8 and a molecular weight of 352.22 g/mol.
The molecular framework of 4,5,7,8,12,13,15,16-Octafluoro[2.2]paracyclophane (C16H8F8) is characterized by fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,5,7,8,12,13,15,16-Octafluoro[2.2]paracyclophane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
