Chemical Structure
Description
The occurrence of (trans,trans)-4-Ethyl-4'-(4-(trifluoromethoxy)phenyl)-1,1'-bi(cyclohexane) is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(trans,trans)-4-Ethyl-4'-(4-(trifluoromethoxy)phenyl)-1,1'-bi(cyclohexane) (CAS 135734-59-7), molecular formula C21H29F3O and molecular weight 354.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (trans,trans)-4-Ethyl-4'-(4-(trifluoromethoxy)phenyl)-1,1'-bi(cyclohexane) (C21H29F3O) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (trans,trans)-4-Ethyl-4'-(4-(trifluoromethoxy)phenyl)-1,1'-bi(cyclohexane) 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.
