Chemical Structure

N-[3,5-Bis(trifluoromethyl)phenyl]-N'-[(1S,2R)-2-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-[(diphenylphosphino)methyl]propyl]thiourea CAS 1333260-44-8 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, N-[3,5-Bis(trifluoromethyl)phenyl]-N'-[(1S,2R)-2-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-[(diphenylphosphino)methyl]propyl]thiourea is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 658.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

N-[3,5-Bis(trifluoromethyl)phenyl]-N'-[(1S,2R)-2-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-[(diphenylphosphino)methyl]propyl]thiourea (CAS 1333260-44-8), molecular formula C31H37F6N2OPSSi and molecular weight 658.75 g/mol, is a CATO reference standard with documented purity and traceability.
