4-Oxo-4H-1-benzopyran-2-carboxylic acid

Description:

4-Oxo-4H-1-benzopyran-2-carboxylic acid, also known as coumarin-2-carboxylic acid, is a chemical compound characterized by its bicyclic structure that includes a benzopyran moiety. This compound features a carbonyl group (C=O) at the 4-position and a carboxylic acid group (–COOH) at the 2-position, contributing to its acidic properties. It is typically a white to pale yellow solid and is soluble in polar organic solvents. The presence of the carboxylic acid group allows for hydrogen bonding, which can influence its solubility and reactivity. This compound is of interest in various fields, including organic synthesis and medicinal chemistry, due to its potential biological activities, such as anti-inflammatory and antioxidant properties. Additionally, it can serve as a precursor for the synthesis of other coumarin derivatives, which are known for their diverse pharmacological effects. Safety data should be consulted for handling, as with any chemical substance, to ensure proper precautions are taken.

Chromone-2-carboxylic acid

CAS: 4940-39-0

Chromone-2-carboxylic acid is a hydrochloric acid analog that is a prodrug for the formation of the active metabolite chromone-2,4-dihydroxybenzoic acid. Chromone-2-carboxylic acid has been shown to have anti-inflammatory properties in vitro and in vivo. It has also been shown to inhibit leukotriene synthesis by blocking the binding of LTC4 to its receptor.
