122-05-4, The chemical industry reduces the impact on the environment during synthesis 122-05-4, name is Pyrazine-2,5-dicarboxylic acid, I believe this compound will play a more active role in future production and life.
A solution of ScCl3¡¤6H2O (30 mg, 0.116 mmol) in distilled water(1.0 ml) was mixed with a solution of H2pzc dihydrate (35 mg, 0.171 mmol) in N,N-dimethylacetamide (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 placedinto a sealed glass tube and kept at 100 C for 48 h. The obtained colorless needle-like crystals were filtered off, washed bytwo portions (2 ml) of acetonitrile and dried in air. The product yield was 18 mg (43%). Elemental analysis: found (%)C 37.2, H 2.8, N 15.2. Calculated for C22H18N8O15Sc2 (%): C 36.8, H 2.5, N 15.5. IR spectrum (KBr), v, cm-1: 417 (w),489 (m), 509 (m), 532 (m), 510 (w), 773 (s), 845 (s), 949 (w), 1016 (w), 1051 (s), 1180 (s), 1200 (w), 1298 (s), 1385 (s),1479 (s), 1666 (s), 2250 (w), 2816 (w), 3100 (w), 3375 (w), 3470 (w).
The chemical industry reduces the impact on the environment during synthesis Pyrazine-2,5-dicarboxylic acid. I believe this compound will play a more active role in future production and life.
