Chemical Structure
Description
4,4'-(Perfluoropropane-2,2-diyl)bis(ethynylbenzene) (CAS 92455-16-8) is a high-purity analytical reference standard with the molecular formula C19H10F6 and a molecular weight of 352.27 g/mol.
4,4'-(Perfluoropropane-2,2-diyl)bis(ethynylbenzene) (C19H10F6) contains fluorine substitution, a polycyclic aromatic system. 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), 4,4'-(Perfluoropropane-2,2-diyl)bis(ethynylbenzene) 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.
