Chemical Structure
Description
1-([1,1'-Biphenyl]-4-yl)-3-((4-fluorophenyl)sulfonyl)propan-1-one (CAS 868256-21-7) is a high-purity analytical reference standard with the molecular formula C21H17FO3S and a molecular weight of 368.42 g/mol.
Structurally, 1-([1,1'-Biphenyl]-4-yl)-3-((4-fluorophenyl)sulfonyl)propan-1-one (C21H17FO3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 368.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
