Description

Description générale

Zinc acetate is primarily utilized as a precursor or catalyst in various synthetic reactions. In organic chemistry, zinc acetate finds application as a reagent in the formation of carbon-carbon bonds. It can facilitate the synthesis of esters, allylic alcohols, and acetals. For example, it can promote the acylation of alcohols, phenols, and amines to form esters, such as the Fischer esterification reaction. Zinc acetate has also been used in the synthesis of metal-organic frameworks (MOFs). MOFs are porous materials consisting of metal ions or clusters coordinated to organic ligands. Zinc acetate can act as a precursor for the formation of MOFs due to its ability to coordinate with organic linkers and form robust networks.

For small scale and high throughput uses, product is also available as ChemBeads (927805)

Application
