New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 4928-87-4, name is 1,2,4-Triazole-3-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 4928-87-4
MnCl2·4H2O (0.198 g, 1.0 mmol) in 3.0 mL of aqueous solution wasslowly added into a flask containing H3dctrz (0.078 g, 0.5 mmol) andpbtrz (0.08 g, 0.5 mmol) in 10.0 mL of aqueous solution. The reactingsolution was kept stirring for 6.0 h. The precipitate was filtrated, andcolourless crystals were isolated from the filtrate within 6 weeks. Yield:0.164 g (52.2% based on Mn(II)). Elemental analysis (EA) for calcd. 1(C6H8N6O6Mn, 315.12): C 16.96, H 1.78, N 22.25; found: C 17.34H 1.94, N 21.22%.
