Description

7-Hydroxycoumarin-4-Acetic Acid is a versatile organic compound belonging to the coumarin family, serving as a key synthetic intermediate and functional building block. Its value lies in its bifunctional structure, which incorporates both a phenolic hydroxyl group and a carboxylic acid moiety, enabling diverse chemical modifications. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors who require a high-purity precursor for developing active ingredients, fluorescent probes, and advanced materials.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel drug candidates, particularly those with anticoagulant, anti-inflammatory, or fluorescent labeling properties.
• Fluorescent Probe Synthesis: Used to create sensitive fluorescent dyes and markers for bioimaging, diagnostic assays, and cellular biology research due to its inherent coumarin fluorophore core.
• Agrochemical Development: Serves as a building block for developing new-generation pesticides and herbicides that leverage the bioactivity of the coumarin scaffold.
• Fine Chemical Synthesis: Employed in organic synthesis to construct more complex heterocyclic compounds, polymers, and specialty chemicals.
• UV Absorber & Stabilizer Precursor: A starting material for manufacturing light stabilizers and UV-absorbing agents used in plastics, coatings, and cosmetics.
• Research & Development: A valuable standard and reagent in academic and industrial R&D labs for studying enzyme inhibition, photochemistry, and material science.

Quality Control

Our 7-Hydroxycoumarin-4-Acetic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 hygroscopic and moisture-sensitive nature, the container must be kept sealed under dry conditions. For long-term storage, consider an inert atmosphere to minimize oxidation.
