Compared with other compounds in its class, the molecular weight of 386.52 g/mol gives 4-Ethoxy-2,3-difluoro-4'-(4-pentylcyclohexyl)-1,1'-biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Ethoxy-2,3-difluoro-4'-(4-pentylcyclohexyl)-1,1'-biphenyl (CAS 123560-47-4) is a high-purity analytical reference standard with the molecular formula C25H32F2O and a molecular weight of 386.52 g/mol.
The molecular framework of 4-Ethoxy-2,3-difluoro-4'-(4-pentylcyclohexyl)-1,1'-biphenyl (C25H32F2O) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
