Description

L-Alanine, Ethenyl Ester (9Ci) is a specialized amino acid derivative where the carboxylic acid group of L-alanine is esterified with vinyl alcohol. This compound serves as a versatile chiral building block and monomer in advanced organic synthesis and polymer chemistry. It is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce the L-alanine moiety under mild conditions or to create novel polymeric materials with specific functionalities.

Application

• Pharmaceutical Intermediate: Used as a chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing the alanine backbone.
• Polymer Science: Acts as a functional monomer for the synthesis of specialty polymers, including biodegradable materials and polymers with tailored side-chain functionalities.
• Peptide Mimetics: Employed in research for creating peptide analogs and modified amino acid structures to study biological activity and stability.
• Agrochemical Synthesis: Serves as a key intermediate in the development of chiral herbicides, fungicides, and plant growth regulators.
• Crosslinking Agent: The vinyl ester group can participate in polymerization reactions, making it useful in creating crosslinked networks for coatings or resins.
• Bioconjugation Chemistry: Useful for modifying biomolecules, where the reactive ester group allows for coupling under controlled conditions.
