Description

7-Methoxy-2-Oxo-2H-Chromene-3-Carbohydrazide is a high-purity, functionalized coumarin derivative that serves as a critical synthetic intermediate for advanced organic synthesis. Its unique structure, featuring both a methoxy-substituted coumarin core and a reactive carbohydrazide moiety, makes it a versatile building block for creating novel compounds with specific biological or material properties. This product is essential for R&D and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new active ingredients or functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting enzymes or receptors where the coumarin scaffold is pharmacologically active.
• Agrochemical Research: Used as a building block for developing new herbicides, fungicides, or plant growth regulators with enhanced efficacy and selectivity.
• Fluorescent Probe & Dye Synthesis: Serves as a starting material for creating advanced fluorescent markers, sensors, or optical brighteners due to the inherent photophysical properties of the coumarin core.
• Coordination Chemistry & Ligand Design: The carbohydrazide group acts as a potential chelating agent for metal ions, useful in creating catalysts or metal-organic frameworks (MOFs).
• Polymer & Material Science: Incorporated into polymer chains to impart specific light-absorbing, emitting, or cross-linking properties to advanced materials.
• Academic & Contract Research: A valuable reagent for methodological studies and discovery chemistry in university and CRO laboratories.
