Used as a reactive intermediate in organic synthesis, particularly in the preparation of trimesic acid derivatives. Acts as a protecting group strategy for carboxylic acids during multi-step syntheses due to its ability to be selectively hydrolyzed. Employed in polymer chemistry to introduce aromatic core structures with defined symmetry, aiding in the development of porous organic frameworks and covalent organic frameworks (COFs). Also utilized in esterification and acylation reactions where controlled release of formate groups is beneficial.
