Description

Oxiranepropanoic Acid, -α--Amino-, Ethyl Ester (9Ci) is a specialized amino acid derivative featuring an epoxide (oxirane) functional group. This unique bifunctional structure makes it a valuable versatile building block for synthesizing complex molecules in pharmaceutical and fine chemical research. It is primarily sought by R&D chemists and process development scientists working on novel active pharmaceutical ingredients (APIs), peptide mimetics, and advanced material precursors.

Application

• Pharmaceutical Intermediate: A key synthon for constructing novel drug candidates, particularly those targeting protease inhibition or requiring specific stereochemistry.
• Peptidomimetic Research: Used to introduce constrained, epoxy-containing amino acid analogs into peptide chains to study structure-activity relationships and enhance metabolic stability.
• Cross-linking Agent: The reactive epoxide group enables its use in modifying polymers, resins, or biomaterials to alter their physical or bioactive properties.
• Chemical Biology Probe Synthesis: Serves as a building block for creating activity-based probes (ABPs) to study enzyme function and mechanism.
• Fine Chemical Synthesis: Employed in the multi-step synthesis of complex natural product analogs and other high-value specialty chemicals.
