Related Products of 122-05-4,Some common heterocyclic compound, 122-05-4, name is Pyrazine-2,5-dicarboxylic acid, molecular formula is C6H4N2O4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
270 mg (1 mmol) of FeCl3.6H2O (Alfa Aesar, 98%) and 204 mg (1 mmol) of 2,5-pyrazinedicarboxylic acid (Aldrich, 98%) are dispersed in 5 ml of DMF (Fluka, 98%) with 0.05 ml of 5M HF (SDS, 50%). The mixture is left in a 23 ml Teflon vessel inserted into a metallic PAAR type bomb for 3 days at 100 C. The solid is recovered by filtration.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Pyrazine-2,5-dicarboxylic acid, its application will become more common.
