Description

4-Ethoxycoumarin is a synthetically derived organic compound belonging to the coumarin family, characterized by an ethoxy substituent at the 4-position. This structural modification makes it a valuable intermediate and building block in advanced organic synthesis, particularly for developing novel pharmaceutical agents and functional materials. It is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries seeking to create compounds with specific biological or photophysical properties. The product is supplied under the identifier CAS NO 35817-27-7.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting anticoagulant, anti-inflammatory, or anticancer pathways.
• Agrochemical Research: Used as a core structure for developing new pesticides, herbicides, and fungicides with enhanced efficacy and selectivity.
• Organic Synthesis Building Block: Serves as a versatile starting material for constructing complex heterocyclic compounds and fine chemicals in R&D laboratories.
• Fluorescent Probe Development: Utilized in material science to create dyes, sensors, and optical brighteners due to the inherent fluorescence of the coumarin scaffold.
• Fragrance and Flavor Chemistry: Acts as an intermediate for synthesizing coumarin derivatives used in perfumery and flavoring agents.
• Academic and Industrial R&D: Essential reference standard and reagent for chemical research in universities and corporate R&D centers.

Quality Control

Our 4-Ethoxycoumarin is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets high-purity standards suitable for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere such as nitrogen or argon for long-term stability. Keep away from strong oxidizing agents.
