Description
As a certified reference material (CRM), trans,trans-4-(3,4-Difluorophenyl)-4'-pentylbicyclohexyl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
trans,trans-4-(3,4-Difluorophenyl)-4'-pentylbicyclohexyl (CAS 118164-51-5) is a high-purity analytical reference standard with the molecular formula C23H34F2 and a molecular weight of 348.51 g/mol.
The molecular framework of trans,trans-4-(3,4-Difluorophenyl)-4'-pentylbicyclohexyl (C23H34F2) is characterized by fluorine substitution, an aromatic ring 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
