Chemical Structure
Description
The occurrence of 1-[3-(4-Chlorobenzenesulfonyl)propoxy]-3-(trifluoromethyl)benzene is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-[3-(4-Chlorobenzenesulfonyl)propoxy]-3-(trifluoromethyl)benzene (CAS 338792-65-7) is a high-purity analytical reference standard with the molecular formula C16H14ClF3O3S and a molecular weight of 378.79 g/mol.
1-[3-(4-Chlorobenzenesulfonyl)propoxy]-3-(trifluoromethyl)benzene (C16H14ClF3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. 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.
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.
