Chemical Structure

1-(2-Amino-5-chloro-4-hydroxyphenyl)-2,2,2-trifluoroethanone 1159977-60-2 2-Trifluoroacetyl-4-chloro-5-hydroxyaniline CAS 1159977-60-2 chemical structure

Description

1-(2-Amino-5-chloro-4-hydroxyphenyl)-2,2,2-trifluoroethanone 1159977-60-2 2-Trifluoroacetyl-4-chloro-5-hydroxyaniline (C8H5ClF3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, 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.
