Description

5-Isoxazolecarboxaldehyde, 3-(2-Propenyloxy)- (9Ci) is a specialized heterocyclic building block featuring a reactive aldehyde group and an allyloxy substituent. This compound matters as a versatile intermediate for synthesizing complex molecules, particularly in pharmaceutical and agrochemical research. It is needed by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and crop protection industries for constructing novel isoxazole-based active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel drug candidates, particularly in medicinal chemistry programs targeting anti-inflammatory, antimicrobial, or neurological disorders.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the isoxazole ring contributes to biological activity.
• Organic Synthesis Building Block: The reactive aldehyde group enables further functionalization through condensation, reduction, or nucleophilic addition reactions for creating diverse chemical libraries.
• Material Science Research: Serves as a precursor for synthesizing functional polymers or ligands for metal-organic frameworks (MOFs) due to its bifunctional nature.
• Academic & Contract Research: Employed in university and CRO (Contract Research Organization) laboratories for methodological studies and the discovery of new chemical entities.
