Description

Phosphoric Acid 3-Chloro-4-Methyl-2-Oxo-2H-1-Benzopyran-7-Yldipropyl Ester is a specialized organophosphorus derivative of a coumarin scaffold, designed for advanced chemical synthesis and material science applications. This compound is valued for its unique molecular architecture, which combines a halogenated benzopyranone core with a phosphoric acid ester, offering specific reactivity and functional properties. It serves as a critical intermediate or functional additive for researchers and manufacturers in the agrochemical, pharmaceutical, and specialty polymer industries seeking to develop novel active ingredients or advanced materials.

Application

• Agrochemical Intermediate: A key building block in the synthesis of novel insecticides, herbicides, or fungicides, leveraging the coumarin and organophosphate motifs for biological activity.
• Pharmaceutical Research: Used as a specialized synthon in medicinal chemistry for developing potential drug candidates, particularly those targeting enzymes where the coumarin structure is relevant.
• Polymer & Material Science: Functions as a flame retardant precursor or a reactive monomer for creating specialty polymers with enhanced thermal stability or specific optical properties.
• Chemical Synthesis: Serves as a versatile phosphorylating or coupling agent in complex organic synthesis for attaching the phosphoric acid ester group to other molecules.
• Dye & Pigment Industry: Acts as an intermediate in the production of advanced colorants and fluorescent markers due to the inherent chromophore properties of the coumarin core.
• Ligand & Chelation Chemistry: Potential use in designing ligands for metal catalysis or extraction processes, utilizing the oxygen-rich binding sites.
