Chemical Structure

N-(3,5-Bis(trifluoromethyl)phenyl)-1-(diphenylphosphoryl)methanethioamide CAS 646497-38-3 chemical structure

Description

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.

N-(3,5-Bis(trifluoromethyl)phenyl)-1-(diphenylphosphoryl)methanethioamide (CAS 646497-38-3) is a high-purity analytical reference standard with the molecular formula C21H14F6NOPS and a molecular weight of 473.37 g/mol.

N-(3,5-Bis(trifluoromethyl)phenyl)-1-(diphenylphosphoryl)methanethioamide (C21H14F6NOPS) contains a steroid core, an amide group, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
