Application of 89-00-9 , The common heterocyclic compound, 89-00-9, name is Pyridine-2,3-dicarboxylic acid, molecular formula is C7H5NO4, its 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.
take 1mol2,3-pyridinedicarboxylic acid, 1.15mol urea ground into a fine powder mixture,Add 1000ml three-necked flask, purged with nitrogen and heated to 189 ,After melting, stirring for 20 min, cooling to room temperature, to give2,3-pyridine diimide;
The synthetic route of 89-00-9 has been constantly updated, and we look forward to future research findings.
