Introductory: The books is suggested that it is appropriate to give the brief note about hereto cyclic compounds bearing Trazine, Altretamine, Triethylenemelamine, Melamine, Atrazine, 4-aminobenzene-1-sulfonyl chloride and azetidinone derivatives disussions.this book is useful for those researcher who are involved to work in such compounds. Heterocyclic compounds of melamine work is also included in this book.

Mr.Tarun M.Patel Dr.A.M.Patel Dr.Shailesh Shah. Introductory: The title of the books was suggested that it is appropriate to give the brief note about hetero cyclic compounds bearing Triazine ring, Naphthalene containing heterocycles as well as brief note on 4-amino benzene-1-sulfonyl chloride.Triazine is the chemical species of six-membered heterocyclic ring compound with three nitrogens replacing carbon-hydrogen units in the benzene ring structure.
