Chemical Structure
Description
1-(4-Fluorophenyl)-3-((2,3,4,5,6-pentamethylbenzyl)sulfonyl)propan-1-one (CAS 868255-95-2) is a high-purity analytical reference standard with the molecular formula C21H25FO3S and a molecular weight of 376.48 g/mol.
The molecular framework of 1-(4-Fluorophenyl)-3-((2,3,4,5,6-pentamethylbenzyl)sulfonyl)propan-1-one (C21H25FO3S) is characterized by a steroid core, a sulfone group, 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.
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), 1-(4-Fluorophenyl)-3-((2,3,4,5,6-pentamethylbenzyl)sulfonyl)propan-1-one 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.
