SMILES: CN(C1=CC=C(C(C2=CC=C(N(C)C)C=C2)=S)C=C1)C
Biological Activity: Thiomichler's ketone (4,4'-Bis (dimethylamino) thiobenzophenone) is a heavy metal complexing agent and a colorimetric/spectrophotometric reagent. Thiomichler's ketone shows selectivity for Hg2+ at pH 3, and exhibits activity towards Pd2+ and Ag+ at pH 3.5. Thiomichler's ketone enables accurate detection of trace Pd2+ by forming an extractable Hg2+ complex via micelle-mediated cloud point extraction, or generating a red coordination complex including Pd (TMK)4. Thiomichler's ketone is applicable for the determination of trace Pd2+ in antibiotics and catalysts of automobile exhaust purifiers[1][2][3].
