Used as a building block in metal-organic frameworks (MOFs) due to its ability to coordinate with metal ions through multiple carboxylic acid groups and nitrogen sites. Its rigid, triangular structure supports the formation of porous, stable frameworks useful in gas storage, separation, and catalysis. Commonly employed in research for designing functional materials with high surface areas. Also explored in proton-conductive materials for fuel cell applications because of its hydrogen-bonding capability and structural stability.
