Description

Aspartic Acid, 2-Ethenyl- is a specialized, non-proteinogenic amino acid derivative featuring a reactive vinyl group. This unique structure makes it a valuable chiral building block and intermediate for advanced organic synthesis. It is primarily sought by research and development teams in the pharmaceutical and fine chemical industries for applications in medicinal chemistry and the development of novel polymers.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in peptide mimetics and enzyme inhibitors.
• Polymer Science: Acts as a functional monomer for the synthesis of specialized polymers, such as poly(amino acid)s and hydrogels, where the vinyl group enables cross-linking or further modification.
• Bioconjugation & Linker Chemistry: Utilized in the design of chemical linkers and probes for bioconjugation strategies, leveraging the reactivity of the vinyl group for selective attachment to biomolecules.
• Agrochemical Research: Employed as an intermediate in the development of new, more selective agrochemicals and plant growth regulators.
• Material Science: Used in the creation of advanced functional materials, including smart coatings and adsorbents, due to its biocompatibility and modifiable side chain.
