s-Triazine derivatives are widely used in agriculture as herbicides due to their ability to inhibit photosynthesis in broadleaf weeds and grasses. These compounds are effective in controlling unwanted plant growth in crops such as corn, sugarcane, and cereals.

In addition to agricultural uses, s-triazine-based compounds serve as key components in flame retardants and cross-linking agents in resins and coatings, enhancing thermal stability and durability.

They are also employed in the synthesis of dyes, optical brighteners, and fluorescent whiteners used in textiles, paper, and detergents.

More recently, functionalized s-triazine scaffolds have gained interest in pharmaceutical and materials science research, particularly in the development of sensors, catalysts, and porous organic networks for gas storage or separation.
