626-05-1 - Reference Information
| purpose | 2, 6-dibromopyridine was synthesized by stiiltype cross-coupling reaction, 2-bipyridine (e. G., 5-cyano-1, 6-dihydro-6-oxy-[3,4 '-bipyridine]-2-carboxylic acid). 2, 6-dibromopyridine is also used as an agent for the synthesis of pyrimidine fungicides, which destroy fungi by allowing copper to circulate at toxic levels on the cell membrane. pharmaceutical intermediates. |
