In the title compound, C(10)H(12)N(6), the two 5,6-dimethyl-1,2,4-triazine halves of the mol-ecule are related by a centre of symmetry. The two triazine rings are coplanar to within a maximum deviation of 0.013 (2) Å from the mean plane of the ring atoms. In the crystal, mol-ecules form layers parallel to the (100) crystallographic plane. Adjacent layers are held together via a C-H⋯π inter-acti...

A first model of the three-dimensional structure of the photosynthetic reaction center of the mutant T1 (SerL223----Ala, ArgL217----His) from Rhodopseudomonas viridis, resistant toward the triazine herbicide terbutryn (2-methylthio-4-ethylamino-6-t-butylamino-s-triazine), has been developed from X-ray data measured to a resolution of 2.5 A. The secondary quinone, QB, which in T1 binds better th...

The pincer ligand 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-methoxy-1,3,5-triazine (bpmt) was used to synthesize the novel [Na(bpmt)2][AuCl4] complex through self-assembly method. In this complex, Na(I) ion is hexa-coordinated with two tridentate N-pincer ligands (bpmt). bpmt units are meridionally coordinated via one short Na-N(s-triazine) and slightly longer Na-N(pyrazole) bonds, resulting in a...

The composition of oilfield water is complex and diverse. development application corrosion inhibitors can effectively inhibit the pipelines equipment by water. ions in produced Jidong Oilfield were determined instrumental analysis chemical analysis. Triazine prepared from ethanolamine formaldehyde as inhibitor was evaluated weight loss method. inhibition experiments carried out ancient samples...

The current study involved synthesis of several new N-Substituted -
 3- chloro -2- azetidinones for 2,4-Diamino-6-phenyl-1,3,5-triazine by two
 steps. first step includes preparation Schiff bases (Al-A6) by
 condensation 2,4-Diamino-6-pheny]-1,3,5-triazine with many substituted
 aldehydes, then the second six azetidinone
 compounds (B1-B6) reaction acetyl chloride the&#...

A simple, specific and reproducible serum iron method is described using the recently synthesized and highly sensitive chromogen, tripyridyl-S-triazine. The absorbance of this chromogen is compared to other iron reagents. Procedural modifications are given for using the Ramsay iron-binding capacity method with this serum iron procedure. The normal values found agree with most of those in the li...

To display favorable fluorescent properties, the non-emissive native nucleosides need to be modified. Here we present a motif that relies on conjugating 5-membered aromatic heterocycles (e.g., thiophene) to a 6-azapyrimidine (1,2,4-triazine) core. Synthetic accessibility and desirable photophysical properties make these nucleosides attractive candidates for enzymatic incorporation and biochemic...

Potent, ligand efficient, selective, and orally efficacious 1,2,4-triazine derivatives have been identified using structure based drug design approaches as antagonists of the adenosine A(2A) receptor. The X-ray crystal structures of compounds 4e and 4g bound to the GPCR illustrate that the molecules bind deeply inside the orthosteric binding cavity. In vivo pharmacokinetic and efficacy data for...
