|  |  | 4-Aminobenzophenone Usage And Synthesis | 
 | Chemical Properties | YELLOW FINE CRYSTALLINE POWDER |  | Uses | 4-Aminobenzophenone is associated with 4-benzoylpyridine and it is used as a frequency doubler for semiconductor lasers. It is used in the preparation of 1-[4-[N,N-bis(trimethylsilyl)amino]phenyl]-1-phenylethylene. It is used as a precursor to prepare 1,2,3-triazoles, pyrimidotriazoles, benzothiazole and pyrimidinone derivatives. It is involved in the formation of coordination complexes with chromium(III). |  | Synthesis Reference(s) | Tetrahedron Letters, 39, p. 1313, 1998 DOI: 10.1016/S0040-4039(97)10877-2 |  | General Description | 4-Aminobenzophenone (4-ABP) is the best derivative of benzophenone with 260 times higher second harmonic generation (SHG) efficiency than potassium dihydrogen phosphate (KDP), growth of high quality bulk crystal still remains a difficult task. |  | Safety Profile | Poison by intraperitoneal route. See also KETONES and AMINES. When heated to decomposition it emits toxic fumes of NOx,. |  | Purification Methods | Dissolve it in aqueous acetic acid, filter and precipitate it with ammonia. This process is repeated several times, then the amine is recrystallised from aqueous EtOH. [Beilstein 14 IV 248.] |
