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.
2,4-Dichloro-N-(4-((3-(trifluoromethyl)phenyl)thio)phenyl)benzamide (CAS 339104-99-3) is a high-purity analytical reference standard with the molecular formula C20H12Cl2F3NOS and a molecular weight of 442.28 g/mol.
2,4-Dichloro-N-(4-((3-(trifluoromethyl)phenyl)thio)phenyl)benzamide (C20H12Cl2F3NOS) contains a steroid core, an amide group, sulfur-containing functionality, 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
