Chlorotriphenylmethane , with CAS number of 76-83-5, can be called [Chloro(diphenyl)methyl]benzene ; 1,1’,1’’-(chloromethylidyne)tris-benzen ; 1,1’,1’’(-Chloromethylidyne)trisben-zene ; chlorotriphenyl-methan ; Methane, chlorotriphenyl- ; alpha-chlorotriphenylmethane ; Benzene, 1,1',1''-(chloromethylidyne)tris- . It is a white solid . Sometimes it is used to introduce the trityl protecting group because it's an alkyl halide. Chlorotriphenylmethane (CAS NO.76-83-5) can be intermediates to produce drug especially for cephalosporins and be synthesized to idoxuridine for the anti-viral effect.
