4,4′-Bis(dimethylamino)thiobenzophenone（Cat No.:M047604）, often abbreviated as Michler’s ketone, is a synthetic organic compound featuring a thiobenzophenone core with two dimethylamino groups attached at the 4 and 4′ positions. This structure grants it strong electron-donating properties and notable photoreactivity. Michler’s ketone is primarily utilized as a photoinitiator in the polymerization of resins and as a dye precursor in the production of various pigments and inks. Its ability to absorb light and subsequently generate reactive species makes it valuable in UV-curing applications, especially in the printing and coatings industries.
