General Description

4-Methylbenzophenone is a photo-initiator for printing inks, mainly applied to the cardboard boxes used for packing. It is reported to be a non-genotoxic carcinogen. However, it can contaminate foodstuffs when it comes in contact with the package contents.

Safety Profile

Poison by intraperitoneal route. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Crystallise the ketone from MeOH, Et2O (m 58-59o) or pet ether. The cis-oxime has m 154o(153-156o) (from EtOH), and the trans-oxime has m 114-116o (from pet ether). [Beilstein 7 H 440, 7 III 2127, 7 IV 1403.]
