| | 4-Oxo-4H-1-benzopyran-2-carboxylic acid Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powder | | Uses | vascular protectant | | Uses | 4-oxo-4H-1-Benzopyran-2-carboxylic Acid acts as an inhibitor of monoamine oxidase A & B. Also functions as a novel type of tyrosine phosphatase 1B inhibitor in studies, due to a structure derived from
formylchromone. | | Uses | Chromone-2-carboxylic acid is used in the cyclic form 3?-oxopyrazolidino[4?,5??2, 3]-chroman-4-one, gives the azide of chromone-2-carboxylic acid, the curtius rearrangement of which is used to synthesize a number of 2-acylaminochromones and it is an orally active antiallergic agent. | | Definition | ChEBI: 4-oxo-1-benzopyran-2-carboxylic acid is a member of chromones. | | General Description | Nasal absorption of 4-oxo-4H-1-benzopyran-2-carboxylic acid has been investigated in the male Wistar rat. |
