Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...

According to Ross (1), there are three main areas in which organotin compounds have product and process utility: (1) heat stabilizers; (2) catalytic agents; (3) biocidal compounds. Organotin derivatives account for the fourth largest production of organometallics amounting to about 3-4 million pounds per year as compared with about 485 million pounds per year for organolead compounds. Originall...

Tin and organotin compounds have been identified in at least 214 and 8 sites, respectively, of the 1,662 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (HazDat 2004). However, the number of sites evaluated for tin and organotin compounds is not known. The frequency of these sites can be seen in Figures 6-1 and 6-2, respectively. All sites w...

Introduction Organotin compounds have been used since the 1960s as an effective antifouling agent in paints applied to ships and aquaculture nets in the marine environment. However, organotin compounds cause damage to nontarget marine organisms by leaching from the coating applied to boat hulls into the marine environment. For Sn analyses, speciation of the organotin compounds has been of great...

The analysis of organotin compounds is becoming increasingly important in both environmental analysis and in food and consumer product analysis. This application note describes a retention time locked (RTL) gas chromatography/mass spectrometry (GC/MS) method for the analysis of derivatized organotin compounds. Three retention time locked libraries are made available, corresponding to three diff...

Several organotin derivatives of 1,2- and 1,7-dicarba-closo-dodecaboranes were synthesized and characterized by (119)Sn Mössbauer, (1)H, (13)C and (119)Sn NMR spectroscopy. Their antitumour activities in vitro against cancerous cell lines of human origin are reported.

Organotin compounds result from the addition of organic moieties to inorganic tin.Thus, one or more tin-carbon bonds exist in each organotin molecule. The organo-tin compounds are ubiquitous in the environment. Organotin compounds have many uses, including those as fungicides and stabilizers in plastics, among others in industry. The widespread use of organotins as antifouling agents in boat pa...
