Quinoxaline, organotin, organofluorine, and formamidine compounds are among the newer pesticide chemicals used for acarine control. Included in these four classes are some of the most selective synthetic organic toxicants currently in the acaricide/insecticide arsenal. Oxythioquinox, Plictran (tricyclohexylhydroxytin), Nissol [2-fluoro-N-methyl-N-(1-naphthyl)acetamide], and chlordimeform are ex...

The interaction of diphenyltin(IV) with selected bioligands having a variety of model functional groups were investigated using the potentiometric technique. The hydrolysis constants of diphenyltin(IV) cation and the step-wise formation constants of the complexes formed in solution were calculated using the non linear least-squares program MINIQUAD-75. The participation of different ligand func...

The concurrent determination of pesticidal and non-pesticidal organotin compounds in several water matrices, using a simultaneous in situ ethylation and liquid-liquid extraction followed by splitless injection mode capillary gas chromatography with pulsed flame photometric detection, is described. The speciation analysis of nine organotin compounds includes low molecular weight low boiling (non...

Organotin compounds are chemicals composed of tin linked to hydrocarbons, used in industrial materials and various biocides and fungicides. As a result, organotin compounds can enter the environment through a number of channels, and can often be found in seawater, seafood, fruits and vegetables, and consumer goods. Due to the toxicity of these compounds, there is a need for analytical methods a...

This review analyzed the literature data on in vitro preclinical study of cytotoxic properties organotin compounds, as well main mechanisms their action. The latter consist interacting with SH groups proteins, initiating oxidative stress, binding to DNA, receptors, activate apoptosis by increasing expression caspases, proapoptotic and decreasing antiapoptotic proteins. Organotin depending donor...

New organotin substituted alpha-anilinomethylphosphonates were prepared and were characterized by FT-IR, 1H- and 13C-NMR spectroscopy and elemental microanalysis.

In the analysis of organotin compounds, derivatization is required in order to achieve more volatile compounds prior to the use of techniques based on GC separation. Derivatization can be considered as one of the main critical steps in organotin analysis, since low yields of derivatization and losses of analytes can easily occur at this stage, and lead to an underestimation of their content in ...
