Ethynyltri-n-butyltin

Description:

Ethynyltri-n-butyltin, with the CAS number 994-89-8, is an organotin compound characterized by the presence of a tin atom bonded to three n-butyl groups and an ethynyl group. This compound typically appears as a colorless to pale yellow liquid and is known for its applications in various fields, including as a biocide and in polymer chemistry. Ethynyltri-n-butyltin exhibits moderate to high toxicity, particularly to aquatic organisms, which necessitates careful handling and disposal. Its structure allows for significant reactivity, particularly in polymerization processes, where it can act as a catalyst or a stabilizer. The compound is also notable for its ability to form stable complexes with various ligands, enhancing its utility in synthetic chemistry. However, due to environmental and health concerns associated with organotin compounds, its use is regulated in many jurisdictions. Proper safety measures should be observed when working with this substance to mitigate potential risks.

Tributylethynylstannane

Controlled Product

CAS: 994-89-8

Tributylethynylstannane is a cross-linking agent that reacts with polymers to form covalent bonds. It is used in the synthesis of polymers for use as adhesives, sealants, and coatings. Tributylethynylstannane reacts with polymers by nucleophilic substitution at the hydroxyl group or halide atom. This reaction mechanism leads to the formation of cross-links between polymer chains, which are required for these materials to be tough and elastic. Tributylethynylstannane can also react with α7 nicotinic acetylcholine receptors on neurons to produce inflammatory diseases such as Parkinson's disease and Alzheimer's disease.
