| Tosyl azide Usage And Synthesis |
| Description | Tosyl azide is a reagent used in organic synthesis. It is prepared by the reaction of tosyl chloride with sodium azide in aqueous acetone. |
| Applications | Tosyl azide is utilized for the introduction of diazo and azide functional groups. Moreover, it is used as a nitrene and a substrate for [3+2] cycloaddition reactions. |
| Safety | Tosyl azide is a very volatile chemical that should be carefully stored and handled. |
| Chemical Properties | Colorless to slight yellow liquid |
| Uses | Used for the introduction of azide and diazo functional groups. It is also used as a nitrene source and as a substrate for [3+2] cycloaddition reactions. |
| Uses | 4-Methylbenzenesulfonyl Azide can be used to target Bcl-2 family proteins to potentially treat cancer. |
| Uses | p-Toluenesulfonyl azide solution can be employed as a reagent along with alkyne, and amine in the three-component coupling reaction for the synthesis of N-sulfonylamidines in presence of copper catalyst. It can also be used in the synthesis of N-sulfonyl-1,2,3-triazoles by azide-alkyne cycloaddition reaction in the presence of copper catalyst. |
