Chemical Structure
Description
5,5'-(Oxybis(methylene))bis(1,3-bis(trifluoromethyl)benzene) (CAS 189446-57-9) is a high-purity analytical reference standard with the molecular formula C18H10F12O and a molecular weight of 470.25 g/mol.
5,5'-(Oxybis(methylene))bis(1,3-bis(trifluoromethyl)benzene) (C18H10F12O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 5,5'-(Oxybis(methylene))bis(1,3-bis(trifluoromethyl)benzene) 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.
