Description

Ethyl 5-Ethyl-1,3,4-oxadiazole-2-carboxylate is a high-purity, versatile heterocyclic building block and ester derivative. This compound is valued for its role as a key synthetic intermediate in the development of complex organic molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and crop protection industries for constructing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, anti-infectives, and metabolic diseases.
• Agrochemical Synthesis: Serves as a building block for developing new herbicides, fungicides, and insecticides with improved efficacy and environmental profiles.
• Material Science Research: Used in the creation of advanced polymers, liquid crystals, and organic electronic materials due to its rigid oxadiazole core.
• Chemical Biology & Proteomics: Employed as a scaffold or linker in the design of molecular probes, enzyme inhibitors, and bioconjugation reagents.
• Academic & Contract Research: Essential for methodological development and exploratory synthesis in university and CRO (Contract Research Organization) laboratories.
• Custom Synthesis & Scale-Up: A starting point for custom manufacturing projects, from gram-scale feasibility studies to multi-kilogram pilot plant production.
