2-Methylbenzophenone Ka CAS 131-58-8
2-Methylbenzophenone ke motsoako oa benzophenone, e leng k'hemik'hale e ntle ea bohlokoa haholo. Ka nako e ts'oanang, li-ketone le tsona ke likarolo tsa mantlha tsa limolek'hule tse ngata tsa manyolo, joalo ka lisebelisoa tse sebetsang, monko o monate le limolek'hule tsa lithethefatsi. Li-ketones tse nkhang hamonate ke li-block tsa bohlokoa haholo tsa ho aha ka har'a organic synthesis, tse teng ka bongata litsing tsa mantlha tsa lihlahisoa tsa tlhaho mme li sebelisoa haholo metsoakong e sebetsang ea biologically.
