Description

Methyl (6-Chloro-7-Methoxy-4-Methyl-2-Oxo-2H-Chromen-3-Yl)Acetate CAS NO 919751-92-1 is a high-purity, synthetically derived chromene derivative, specifically a coumarin ester. This compound serves as a critical advanced pharmaceutical intermediate and a versatile building block in organic synthesis. It is primarily required by R&D chemists and process development teams in the pharmaceutical, agrochemical, and fine chemical industries for the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting specific enzyme pathways.
• Agrochemical Research: Building block for developing new-generation herbicides, fungicides, or plant growth regulators with enhanced activity.
• Organic Synthesis: Versatile synthon for constructing complex heterocyclic frameworks and functionalized coumarin derivatives in academic and industrial research.
• Material Science: Potential monomer or additive in the development of specialty polymers and advanced functional materials.
• Fluorescent Probe Development: Core structure for creating sensitive chemosensors and biological imaging agents due to the inherent chromophore properties of the coumarin scaffold.
