1,3,5-Triazine derivatives find wide applications as bioactive compounds and drugs, components of polymer compositions, reactive dyes, energetic materials, reagents for organic synthesis, combinatorial and analytical chemistry. In this book, the authors present topical research in the study of the synthesis, applications and toxicity of triazines. Topics discussed include polynitromethyl 1-1,3,5 triazines; application of triazine based dendrimers as drug delivery agents; biodegradation of s-triazine herbicides in soil/surface water environments and synthesis and properties of heat-resistant polymers containing triaryl-s-triazine moiety.
