Description

4-[3-(3,4-Dimethylphenyl)-1,2,4-Oxadiazol-5-Yl]Phthalazin-1(2H)-One is a high-purity, advanced pharmaceutical intermediate and research chemical with a complex heterocyclic structure. This compound is valued for its role as a critical building block in the synthesis of novel active pharmaceutical ingredients (APIs) and agrochemicals. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for developing new therapeutic and crop protection agents.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, inflammation, and oncology.
• Agrochemical Research: Serves as a core scaffold for developing new-generation herbicides, fungicides, and insecticides with specific modes of action.
• Chemical Biology Probe: Used in academic and industrial research to study enzyme inhibition and protein-ligand interactions due to its distinctive oxadiazole-phthalazinone pharmacophore.
• Material Science Research: Investigated as a potential monomer or additive for creating specialty polymers with unique thermal or optical properties.
• Contract Research & Development (CRO/CMO): Supplied to research organizations and custom manufacturers for client-specific synthesis projects and library generation.
