Description

Compared with other compounds in its class, the molecular weight of 358.46 g/mol gives 4-Ethoxy-2,3-difluoro-4'-(trans-4-propylcyclohexyl)biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Ethoxy-2,3-difluoro-4'-(trans-4-propylcyclohexyl)biphenyl (CAS 189750-98-9), molecular formula C23H28F2O and molecular weight 358.46 g/mol, is a CATO reference standard with documented purity and traceability.

4-Ethoxy-2,3-difluoro-4'-(trans-4-propylcyclohexyl)biphenyl (C23H28F2O) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4-Ethoxy-2,3-difluoro-4'-(trans-4-propylcyclohexyl)biphenyl 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.
