4,4′-Bis(dimethylamino)benzophenone(CAT: R069833), also known as Michler’s ketone, is an aromatic ketone featuring two dimethylamino groups para-substituted on each benzene ring of the benzophenone core. This compound is widely used as a photosensitizer, chemical intermediate, and dye precursor in the synthesis of triarylmethane dyes, pigments, and optical brighteners. Its strong electron-donating dimethylamino groups enhance its chromophoric properties, making it highly responsive to UV and visible light. Michler’s ketone is also employed in photopolymerization processes and as a sensitizer in photoresists and coatings. Its well-defined structure and photoactive behavior make it valuable in both industrial applications and photochemical research.
