| Coumalic acid Usage And Synthesis |
Chemical Properties | pale yellow to pale brown powder | Uses | Coumalic acid undergoes thermal reaction with 1,3-butadiene to yield dimethyl tricycle[3.2.1.02,7]oct-3-ene-2,4-dicarboxylate. | Definition | ChEBI: Coumalic acid is a pyranone. | General Description | Decarboxylates to α-pyrone, a Diels-Alder diene. | Purification Methods | The acid crystallises from MeOH. The methyl ester has m 73-74o (from pet ether) and b 178-180o/60 mm. [Beilstein 18/8 V 120.] |
