Melamine poisoning has become widely publicized after a recent occurrence of renal injury in infants and children exposed to melamine-tainted milk in China. This renal damage is believed to result from kidney stones formed from melamine and uric acid or from melamine and its cocrystallizing chemical derivative, cyanuric acid. However, the composition of the stones and the mechanism by which the...

A significant group of compounds arise from substituted s-triazine derivatives that have tripodal heterocyclic compound. Compounds classified as possible created the largest and most diverse family organic compounds. In this study, we reported a new template has been syntheses cyanuric chloride its diamine derivative. The desired triamine 2, 4, 6-tris (p-aminoaanilino)-1, 3, 5-triazine (C21H21N...

Chloroisocyanurates are commonly added to outdoor swimming pools to stabilize chlorine disinfectants. The chloroisocyanurates decompose slowly to release chlorine and cyanuric acid. Studies conducted to determine if the chloroisocyanurates might be toxic to swimmers showed that they were not and that ingested cyanuric acid passed through the body unmetabolized. This fact was used to determine t...

OBJECTIVE To develop an analytical method for simultaneously qualitative and quantitative determination of melamine and triazine-related by-products including ammelide, ammeline, and cyanuric acid in milk and milk products by gas chromatography-tandem mass spectrometry (GC-MS/MS). METHODS Melamine and triazine-related by-products namely ammelide, ammeline and cyanuric acid in the samples were...

Pseudomonas sp. strain ADP is the model strain for studying bacterial degradation of the s-triazine herbicide atrazine. In this work, we focused on the expression of the atzDEF operon, involved in mineralization of the central intermediate of the pathway, cyanuric acid. Expression analysis of atzD-lacZ fusions in Pseudomonas sp. strain ADP and Pseudomonas putida showed that atzDEF is subjected ...

The intentional adulteration of pet food with melamine and cyanuric acid has been implicated in the kidney failure and death of a large number of cats and dogs in the United States. Although individually these compounds present low toxicity in a range of experimental animals, coexposure can lead to the formation of melamine cyanurate crystals in the nephrons and eventual kidney failure. Given t...

Novel red and purple reactive disperse silicon-containing dyes were designed and synthesized using p-nitroaniline and 6-bromo-2,4-dinitro-aniline as diazonium components, the first condensation product of cyanuric chloride and 3-(N,N-diethyl)amino-aniline as coupling component, and 3-aminopropylmethoxydimethylsilane, 3-aminopropylmethyldimethoxysilane, and 3-aminopropyltrimethoxysilane as silic...
