Description
CATO manufactures 1,2-Bis(4-hydroxyphenyl)-1,1,2,2-tetrafluoroethane 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.
1,2-Bis(4-hydroxyphenyl)-1,1,2,2-tetrafluoroethane (CAS 433719-69-8) is a high-purity analytical reference standard with the molecular formula C14H10F4O2 and a molecular weight of 286.22 g/mol.
The molecular framework of 1,2-Bis(4-hydroxyphenyl)-1,1,2,2-tetrafluoroethane (C14H10F4O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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.
