Adding a certain compound to certain chemical reactions, such as: 122-05-4, name is Pyrazine-2,5-dicarboxylic acid, belongs to pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 122-05-4, Product Details of 122-05-4
A ScCl3ยท6H2O (30 mg, 0.116 mmol) solution in distilled water (1.0 ml)was mixed with a H2pzc dihydrate solution (35 mg, 0.171 mmol) in N,N-dimethylformamide (1.0 ml). Acetonitrile (2.0 ml)and 0.25 ml of concentrated hydrochloric acid were added to the mixture. The prepared reaction mixture was placed intoa sealed glass tube and kept at 100 C for 24 h. The obtained colorless plate-like crystals were filtered off, washed by twoportions (2 ml) of acetonitrile and dried in air. The product yield was 40 mg (89%). Elemental analysis: found (%) C 37.1,H 3.4, N 14.2. Calculated for C24H24N8O16Sc2 (%): C 37.4, H 3.1, N 14.5. IR spectrum (KBr), v, cm-1: 392 (m), 427 (m),490 (m), 510 (s), 530 (s), 694 (m), 776 (s), 846 (s), 950 (w), 1051 (s), 1121 (m), 1179 (s), 1298 (s), 1386 (s), 1477 (s),1673 (s), 2510 (w), 2818 (w), 3104 (w), 3380 (w), 3491 (w).
