Organotin compounds are widely applied as pesticides; as preservatives of wood, paper, textiles, leather, and glass; in heat/light protection of PVC plastics; and in antifouling paints. The use of dialkyltin compounds can cause hepatotoxicity, whereas trialkyltin compounds can cause neurotoxicity.
What is meant by organotin compound?
Definition of organotin compounds: Compound that contains both tin and carbon.
Is organotin toxic?
Some of the organotin compounds can be quite toxic causing neurotoxicity, hepatotoxicity, renal toxicity or dermal toxicity (1). The organotins can be classified into two groups based on their use.
What is tin formula?
Molecular Formula. Sn+2. Synonyms. Tin(2+) Tin (II) ion.
How do you make organotin?
Organotin compounds can be synthesised by numerous methods. Classic is the reaction of a Grignard reagent with tin halides for example tin tetrachloride. An example is provided by the synthesis of tetraethyltin: 4 EtMgBr + SnCl4 → Et4Sn + 4 MgClBr.
Why is organotin toxic?
Inhaling tin as dust or fumes may cause a benign pneumoconiosis in exposed workers. The organotin compounds can be divided into alkyltin and aryltin compounds. The trimethyl and triethyltin compounds are well absorbed from the gastrointestinal tract and are the most toxic in this group.
What is element 50 on the periodic table?

What is the limit of content of organotins in products?
The EU commission subsequently incorporated this decision into Annex XVII of Reach Regulations. The requirements and the date of entry into force differ per substance and article. Typically, the limit of content for all these compounds in products is 0.1% per weight. Why choose Eurofins | BLC to conduct your organotins testing and analysis?
How do organorganotin compounds reach humans?
Organotin compounds reach humans primarily through the diet, in particular through contaminated water, meat, and fish products. H.K. Okoro, R.G. Snyman, in Encyclopedia of Toxicology (Third Edition), 2014
What is eueu – organotin restrictions?

What are organotin compounds?
Organotin compounds, or stannanes, are chemical compounds based on tin element bonded to carbon. These compounds are classified by the number of organic functional groups bond to tin i.e. tetra-, tri-, di- and mono-organotin compounds.
