31037-02-2, The chemical industry reduces the impact on the environment during synthesis 31037-02-2, name is Ethyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate, I believe this compound will play a more active role in future production and life.
The ligand, L (0.169 g; 1 mmol), was dissolved in hot MeOH (5 cm3), and Cu(NO3)2¡¤3H2O (0.12 g; 0.5 mmol) was added. Three days later, brown plate-like microcrystals were filtered and washed with MeOH and Et2O. Yield: 0.159 g (60%). Calcd. (Found) for CuC14H22N8O10: C, 31.97; H, 4.18; N,21.30. (C, 31.76; H, 4.29; N, 21.13). IR bands [ v/cm-1]:3490, 3441, 3346, 1682, 1633, 1460, 1384, 1220, 1126, 771. Molar conductivity, LambdaM (S cm2 mol-1): 131 (DMF).
