Cyanuric acid, used as chlorine stabilizer in swimming pool waters, has a relatively minor effect on the algicidal efficiency of free chlorine. The toxicity of free chlorine to three swimming pool algae was reduced slightly by 25 mg of cyanuric acid per liter if inhibiting, but less than algicidal, concentrations of chlorine were employed. Higher stabilizer concentrations (50, 100, and 200 mg/l...
Bicyclic isoxazolines and isoxazoles are obtained in good yields by proceeding through a convenient one-pot, two-step procedure utilizing 2,4,6-trichloro-1,3,5-triazine (TCT) as a dehydrating agent.
A method for determining tissue sites of plasma protein degradation is described as applied to studies of low density lipoprotein (LDL) catabolism in swine. The method is based on the fact that sucrose is not degraded by lysosomal enzymes and thus accumulates in lysosomes. [(14)C]Sucrose was activated with cyanuric chloride and covalently coupled to the LDL protein. Studies in cultured fibrobla...
Ethylene-bridged bis(hydroxylamino-1,3,5-triazine) compounds, that may serve as tetradentate ligands, were synthesized in three steps from 2,4,6-trichloro-1,3,5-triazine. These compounds demonstrate different rotation restrictions around the C(Ar)-N bonds due to their distinctive electronic structure as apparent from their resonative contributors. A dinuclear complex Ti 2(mu-L)2(OiPr)4 (L = bis...
An on-line microdialysis/high-performance liquid chromatography method was developed for the simultaneous determination of melamine and cyanuric acid in non-dairy coffee creamer. To collect these analytes from aqueous samples, the microdialysis system featured a microdialysis probe incorporating a polyarylethersulfone membrane and employed 0.05 M HCl in 0.1% (v/v) MeOH as the perfusate, with o...
Isolation of bacteria able to utilize s-triazines as the sole and limiting nitrogen sources for growth is described. Three strains of Pseudomonas (A, D, and F) and two strains of Klebsiella pneumoniae (90 and 99) were examined. Strains D and F utilized N-ethylammelide, N-isopropylammelide, ammeline, ammelide, cyanuric acid, and ammonium ion as nitrogen sources. Strain A utilized melamine, ammel...
Multidentate ligands involving tethered pyridyl groups coordinated to transition metal ions have been frequently used mimic the 3-histidine (3H), 2-histidine-1-carboxylate (2H1C) brace motifs or other combinations of histidine and carboxylate endogenous ligating residues found in bioinorganic metalloenzymes. It is interest immobilize these ligand chelates onto heterogeneous supports. This, howe...
