Product overview
CAS 51446-31-2 is an aromatic carboxylic acid containing fluorine substituents on aromatic rings, carboxyl groups, hydroxy groups. Under suitable reaction conditions, its carboxyl groups may be used for ester or amide formation. These are structure-based potential transformations, not verified specific downstream applications.
Application areas
Depending on the synthesis route and project requirements, this product may also be suitable for other related organic synthesis applications.
Potential uses
- The carboxylic acid group may be activated for amide coupling with suitable amines or esterified to prepare carboxylate derivatives. The phenolic hydroxyl group may be O-alkylated to form aryl ethers or esterified to create phenolic ester derivatives.
