The photodegradation of Azinphos-ethyl (1) in chloroform and methanol solution has been studied. 3,4-D ihydro-3-m ethyl-4-oxobenzo[d][l,2,3]triazine (3), 3,4-dihydro-4-oxo-benzo[d][l,2,3]triazine (5), 0 ,0-d iethyl-0(3-m ethylbenzo[d][l,2 ,3]triazine-4-yl)phosphate (8), N-methylanthranilic acid (11) (in methanol: methyl ester 12), and sulfur have been isolated and charac­ terized as photoproduc...

To help elucidate the mechanism of dechlorination of chlorinated triazines via metallic iron, terbutylazine (TBA: 2-chloro-4-ethylamino-6-terbutylamino-1,3,5-triazine), deisopropyl atrazine (DIA: 2-amino-4-chloro-6-ethylamino-1,3,5-triazine), and chlorinated dimethoxy triazine (CDMT: 2-chloro-4,6-dimethoxy-1,3,5-triazine) were degraded via zero valent iron under controlled pH conditions. The lo...

Structure-activity relationships of the 3,5-diamino-piperidinyl triazine series, a novel class of bacterial translation inhibitors, are described. Optimization was focused on the triazine C-4 position in which aromatic substituents that contained electron-withdrawing groups led to potent inhibitors. The initial lack of antibacterial activity was correlated with poor cellular penetration. Whole ...

This work includes synthesis a series of some new derivatives triazine from reaction between the sulfur amino acid (L-cysteine) and different aldehydes in dry ethanol to obtain thiazolidine ring as diastereo isomers (Cis Trans)- 2- alkylthiazolidine-4- carboxylic acids (1).

The metabolism of 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) in the resistant species, corn (Zea mays L.) and sorghum (Sorghum vulgare Pers.) was not the same. In corn, atrazine was metabolized via both the 2-hydroxylation and N-dealkylation pathways while sorghum metabolized atrazine via the N-dealkylation pathway. Atrazine metabolism in corn yielded the metabolites, 2-hydrox...

In the title compound, [Fe(CH(3)CN)(3)(C(29)H(27)N(5)OP(2))](BF(4))(2)·2CH(3)CN, the Fe(II) ion is octa-hedrally coordinated by a meridionally chelating tridentate pincer-type PNP ligand derived from 2,6-diamino-4-eth-oxy-1,3,5-triazine and by three acetonitrile mol-ecules. The four Fe-N bond lengths range from 1.9142 (12) to 1.9579 (11) Å, while the Fe-P bonds are 2.2452 (4) and 2.2506 (4) Å [...

Bacteria were isolated that could utilize quantitatively the s-triazine herbicide prometryne [N,N' -bis(1-methylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine] or ametryne [N-ethyl-N'-(1-methylethyl)-6-(methylthio)-1,3,5-triazine- 2,4-diamine], or both, as a sole source of sulfur for growth. The success of enrichments depended on previous exposure of the soil inoculum to s-triazine herbicides...

A new dimension: The doping of amorphous poly(triazine imide) (PTI) through ionothermal copolymerization of dicyandiamide with 4-amino-2,6-dihydroxypyrimidine (4AP) results in triazine-based carbon nitrides with increased photoactivity for water splitting compared to crystalline poly(triazine imide) (PTI/Li(+)Cl(-), see picture) and melon-type carbon nitrides. This family of carbon nitride semi...

Introduction The presence of certain heterocyclic rings with nitrogen atoms in an organic polymer may significantly improve its thermal stability. For typical polyurethane foams, the upper temperature range of save usage is usually considered to be 90-110°C [1, 2]. This limit can be improved by applying an oligoetherol component containing a thermostable heterocyclic ring with nitrogen atoms, s...

The properties relevant to pharmacokinetics and pharmacodynamics of four series of synthesized s-triazine derivatives have been studied by Quantitative structure-retention relationship (QSRR) approach. The chromatographic behavior of these compounds was investigated by using reversed-phase high performance thin-layer chromatography (RP-HPTLC). Chromatographic retention (RM0) was correlated with...
