1. Catalysts for organic synthesis: Some organotin compounds have important catalytic functions, such as catalysts for the synthesis of acrylonitrile in industrial production, or catalysts for organic chemical reactions in organic synthesis, such as tin Acetylacetone, tin alkylate and tributyltin, etc.

2. Metalorganic chemical reagents: Many organotin compounds have Properties of chemical reagents, such as organotin oxides and organotin halides, etc.

3. Antifungal agents and preservatives: Some have antibacterial and antibacterial properties Organotin compounds with fungal action are widely used in wood preservation, paint and plastic material protection, such as hexamethylbis(bisphenoxy)tin, hexa(tert-butyl)tin and hexa(trimethyloxy)tin wait.

4. Heat stabilizers and light stabilizers: Some organic tin compounds act as thermal Stabilizers and light stabilizers are widely added to materials made of thermoplastics, paints, rubber, etc. to improve the heat resistance and light resistance of these materials.

Although organotin compounds are widely used, there are also environmental and health concerns Potential problems, so its use and emissions need to be strictly controlled and managed.
