Coumalic acid Chemical Properties,Uses,Production
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.]
