What is Triphenyltin hydroxide?
Triphenyltin hydroxide (CAS 76-87-9), commercially known as fentin hydroxide, is an organotin biocide used in agricultural crop protection.
Where is Triphenyltin hydroxide used?
- Fungicide and algaecide controlling fungal pathogens and algae in targeted field applications
- Registered against late blight and Cercospora leaf spot in potato and sugar beet crops
- Algae control in rice paddy cultivation, applied directly to flooded fields to suppress aquatic weed competition
- Specialty crop programs: tank-mix partner with other fungicides to broaden disease control spectrums
- Industrial antifouling formulations have historically incorporated organotin compounds of this class to prevent biofouling on marine surfaces.
Commercial specifications
- Purity specifications vary by supplier and regional registration requirements
