Applicazioni

Vinylacetic acid used in the preparation of strained nitroso Diels-Aldrer adducts which undergo a domino ROC metathesis in the presence of Ru-carbene catalysts and olefins. It is used in the synthesis of polyethylene glycolated boltorn coatings. It was used to study the inhibition of the enzyme-catalyzed conversion of D-tyrosyl- phenylalanyl-glycine to D-tyrosyl-phenylaline amide by non-peptide carboxylic acids.

Note

Store at 4°C. Protect from heat. Store away from oxidizing agents. Incompatible with oxidizing agents, heat, Bases, Reducing agents.
