Used as an intermediate in the synthesis of dyes and pigments, particularly for reactive dyes that bond covalently with fibers like cotton and rayon. Its aldehyde and triazine groups allow for sequential functionalization, making it valuable in creating complex dye molecules with high color fastness. Also employed in the development of pharmaceuticals and agrochemicals due to its ability to act as a building block in heterocyclic chemistry. Additionally, it finds use in polymer chemistry for modifying resins and enhancing cross-linking properties.
