Description

7-Fluorocinnolin-4(3H)-One is a high-purity fluorinated cinnolinone derivative, a valuable heterocyclic building block in advanced organic synthesis. Its core value lies in its unique molecular scaffold, which is critical for modulating the biological activity and physicochemical properties of target compounds. This intermediate is primarily needed by pharmaceutical R&D teams and fine chemical manufacturers engaged in developing novel active pharmaceutical ingredients (APIs), agrochemicals, and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly in kinase inhibitor and anticancer agent research.
• Agrochemical Research: Used in the development of new herbicides and fungicides, where the fluorine atom and cinnolinone core can enhance bioactivity and environmental stability.
• Material Science: Acts as a building block for creating specialized organic electronic materials and photoactive compounds.
• Chemical Biology: Employed as a probe or labeling agent in biochemical studies due to its fluorinated aromatic structure.
• Academic & Contract Research: Essential for methodological development and exploratory synthesis in university and CRO laboratories.
