| 3-Amino-5-mercapto-1,2,4-triazole Usage And Synthesis |
| Chemical Properties | white to light beige crystalline powder |
| Purification Methods | Recrystallise the triazole from H2O and dry it in vacuo. The acetyl derivative has m 325o(dec) after recrystallisation from H2O. [Beilstein 26 III/IV 1351.] It has also been recrystallised from EtOH/H2O (3:1, 1g in 50 mL, 50% recovery), m 300-302o (dec subject to heating rate), ( max 263nm, log 4.12). The S-benzyl derivative, when crystallised from *C6H6/EtOH (20:1), or CHCl3/Et2O has m 109-111o [Godfrey & Kruzer J Chem Soc 3437 1960, Beilstein 26 III/IV 1351.] |
