Chemical Structure
Description
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.
4-((2-(4-Chlorophenyl)-2-Ethylbutoxy)Methyl)-1-Fluoro-2-Phenoxy-Benzene (CAS 83493-19-0) is a high-purity analytical reference standard with the molecular formula C25H26ClFO2 and a molecular weight of 412.92 g/mol.
4-((2-(4-Chlorophenyl)-2-Ethylbutoxy)Methyl)-1-Fluoro-2-Phenoxy-Benzene (C25H26ClFO2) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-((2-(4-Chlorophenyl)-2-Ethylbutoxy)Methyl)-1-Fluoro-2-Phenoxy-Benzene 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.
