4-(Dimethylamino)benzophenone Usage And Synthesis

Chemical Properties

YELLOW CRYSTALLINE POWDER OR CRYSTALS

Uses

4-(Dimethylamino)benzophenone is an important organic intermediate. It can be used in agrochemical, pharmaceutical and dyestuff field.

Synthesis Reference(s)

Synthesis, p. 544, 1986 DOI: 10.1055/s-1986-31696
Tetrahedron Letters, 34, p. 7595, 1993 DOI: 10.1016/S0040-4039(00)60409-4

Purification Methods

Crystallise the pale green p-dimethylaminobenzophenone from EtOH. Dissolve 100g in 600mL of boiling EtOH, add 5g of charcoal, cool, isolate the solid by centrifugation and similarly wash the pale crystals with ice-cold EtOH. When filtered by suction, EtOH solution remains on the crystals and turns deep green in air. Dry it in a vacuum and store it in the dark. The hydrazone has m 128-130o and forms a ketyl with potassium. [Hurd & Webb Org Synth Coll Vol I 217 1941, Beilstein 14 H 82, 14 I 288, 14 III 218, 14 IV 248.]
