Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, This compound has unique chemical properties. The synthetic route is as follows., Safety of 3,5-Dibromo-1H-1,2,4-triazole
To a solution of 3,5-dibromo-lH-l,2,4-triazole (5.00 g, 22.04 mmol) in CH3CN (50 ml) was added 2-(2-bromoethoxy)tetrahydro-2H-pyran (5.07 g, 24.24 mmol) and DIPEA (4.00 ml, 24.24 mmol). The resulting solution was heated at 90 C for 3 h.Subsequently, the mixture was cooled and diluted with EtOAc (100 ml). The resulting solution was then washed with a sat. aq. solution of NaHC03 and brine. The organic layer was dried (MgSC^) and concentrated under reduced pressure. The residue was purified by flash column chromatography over silica gel (eluent: DCM/MeOH(NH3) from 100/0 to 97/3). The product fractions were collected and concentrated in vacuo, yielding 6.00 g of intermediate 56 (77 %).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7411-23-6.
