In this work, the degradation of 2-chloro-4,6-diamino-1,3,5-triazine in aqueous solutions by photo-Fenton process has been investigated. The preliminary results have shown that the degradation of 2-chloro-4,6-diamino-1,3,5-triazine by photo-Fenton process is more rapid and more effective than Fenton and UV/H2O2 processes. The effects of certain experimental parameters on kinetics and efficiency...

Herein we report a parallel solid-phase synthesis of 1,3,5-triazine based nucleoside analogues by a three-step substitution, starting from 2,4,6-trichloro-1,3,5-triazine. A library of 80 galactosyl-1,3,5-triazine compounds was prepared in high purity without extensive reaction conditions or tedious purification, suggesting the generality of this method.

When crystallized from ethanol, 7,7-dimethyl-2-pyridin-4-yl-6,7-dihydro-1,2,4triazolo[1,5-a][1,3,5]triazin-5-amine forms crystals which have monoclinic (P21/n) symmetry with unit cell dimensions a = 7.3326(5) Å, b = 19.4897(14) Å, c = 8.6586(6) Å, α = 90°, β = 106.069(2)°, γ = 90°, V = 1189.06(14) Å, Z = 4. The triazine ring in the molecule has a flattened boat conformation with gem-dimethyl gr...

Bleaching of polymeric materials can be achieved by blending or surface treatment with fluorescent brighteners, FBs [1]. In both cases the FB migrates with time, and the degree of whiteness decreases. The introduction of polymerizable groups into the FB makes it applicable in the copolymerization process with vinyl monomers, resulting in the formation of covalent bonds in the polymer molecule. ...

Anion receptors bearing p electron-deficient arenes have attracted increasing interest during the past decade. The anion–p interaction between charge neutral electron-deficient aromatic rings, as predicted by theoreticians, has been evidenced experimentally both by solid state and solution investigations. For example, in the solid state, while weaks-interaction in which anions interact with p e...

Enrichment cultures utilizing deethylsimazine (6-chloro-N-ethyl-l,3,5-triazine-2,4-diamine) as a sole nitrogen source were obtained from so5 that had had long exposure to s-triazine herbicides. A bacterium was isolated that utilized deethylsimazine quantitatively as a nitrogen source for growth, but only 1 mol of nitrogen was obtained/mol of deethylsimazine, whereas all six atoms in melamine we...

triazine derivatives are small synthetic peptides with no apparent toxicity and high target specificity in central nervous system. hippocampal tissue is the most vulnerable area in the alzheimer’s disease (ad). the aim of this study was to investigate the neuroprotective effect of triazine in ad induced by intra-cerebro-ventricular (i.c.v.) administration of streptozotocine (stz). male wistar, ...

6-Methyl-2-phenyl-7H-Oxazolo [3,2-b] [1,2,4] triazine (1) undersent ting transformation on treatment with ammonia and primary amines to afford the corresponding imidazol [1,2-b][1,2,4] triazine (2). Treatment of (1) with hydrazine hydrate gave the corresponding 3-aryl-4H-1,2,4- triazino [4,3-b][1,2,4] triazin-8 (1H)-one (3).
