Description

1,2,5-Oxadiazole-3-Carboxylicacid,Methylester,2-Oxide(9Ci) is a specialized heterocyclic building block of significant interest in advanced organic synthesis. Its unique 1,2,5-oxadiazole (furazan) core, functionalized with a carboxylic acid methyl ester and an N-oxide group, makes it a versatile precursor for constructing complex molecular architectures. This high-purity intermediate is primarily sought by research and development teams in the pharmaceutical and agrochemical sectors for the synthesis of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the research and development of new drug candidates, particularly those targeting neurological or metabolic pathways.
• Agrochemical Synthesis: Used in the creation of novel herbicides, fungicides, or insecticides, leveraging its heterocyclic structure for bioactivity.
• Energetic Materials Research: Serves as a precursor in the development of new high-energy-density materials (HEDMs) and propellants due to the furazan scaffold.
• Ligand and Catalyst Development: Employed in organometallic chemistry to create novel chelating ligands or catalysts for asymmetric synthesis.
• Functional Material Precursor: Used in the synthesis of advanced polymers, dyes, or electronic materials requiring specific heterocyclic components.
• Academic & Industrial R&D: A valuable compound for methodological studies in organic chemistry and the exploration of new chemical spaces.
