Description

6-Chloro-2-Oxo-2H-Chromene-3-Carbonyl Chloride is a high-purity, reactive chemical intermediate essential for advanced organic synthesis. Its bifunctional nature, featuring both an acid chloride and a chlorinated coumarin core, makes it a critical building block for constructing complex heterocyclic molecules. This compound is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those with coumarin-based structures for therapeutic applications.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the chlorinated coumarin moiety can impart specific biological activity.
• Dye & Pigment Manufacturing: Serves as a building block for creating specialized fluorescent dyes and light-absorbing pigments.
• Organic Light-Emitting Diodes (OLEDs): Acts as a starting material for synthesizing electron-transport or emissive layer materials in electronic displays.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D focused on heterocyclic chemistry and material science.
• Polymer Modification: Can be used to introduce functional coumarin groups into polymer chains to alter physical or optical properties.

Quality Control

Our 6-Chloro-2-Oxo-2H-Chromene-3-Carbonyl Chloride is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, confirming compliance with customer specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, open flames, and incompatible materials such as strong bases and oxidizing agents.
