Triphenyltin compounds
Triphenyltin compounds (abbreviated TPT from English triphenyltin , also referred to as " Fentin " compounds) are organometallic compounds of tin with three phenyl groups .
use
Triphenyltin compounds are highly effective biocides . Together with tributyltin compounds, they were part of many antifouling paints that were used to protect ships from vegetation (until around 1990). They are also used as fungicides in agriculture because, among other things, they inhibit the respiration of fungi by blocking oxidative phosphorylation . In Germany, however, registration was withdrawn in 2001. In the EU, the use of organotin compounds for underwater painting on ships has been banned since 2003. Since 2006, TPT compounds may no longer be marketed as biocides in the EU.
safety instructions
They get into the environment during production and use. TPT compounds are lipophilic and adsorb strongly on particles. They are only broken down relatively slowly in the environment and have a high bioaccumulation potential . Triphenyltin compounds are toxic, toxic to reproduction and act as strong endocrine disruptors (androgenic effects).
