Description

3-Ethyl-5-Isoxazolecarbonitrile (Saltdata: Free) is a high-purity, versatile heterocyclic nitrile building block essential for advanced organic synthesis. Its unique isoxazole core functionalized with a nitrile group makes it a critical intermediate for developing novel pharmaceuticals and agrochemicals. This compound is primarily sought after by research institutions and industrial R&D departments engaged in medicinal chemistry, crop protection, and materials science.

Application

• Pharmaceutical Intermediate: A key synthon for the development of new active pharmaceutical ingredients (APIs), particularly in kinase inhibitor and anti-inflammatory drug discovery programs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides, leveraging the bioactivity of the isoxazole ring.
• Material Science Research: Serves as a precursor for functional polymers, liquid crystals, and other advanced materials requiring specific heterocyclic architectures.
• Chemical Biology & Proteomics: Employed as a building block for activity-based probes and other tools used in biochemical research and target identification.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of client-specific target molecules.
