Description

7-(Oxiranyloxy)-2H-1-Benzopyran-2-One is a specialized organic compound featuring a coumarin core functionalized with an oxiranyl (epoxide) group, making it a valuable synthetic intermediate. This unique structure provides a reactive epoxide handle for further chemical modifications, which is critical for developing advanced materials and fine chemicals. It is primarily sought by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and polymer sectors for use in synthesis and product development.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for compounds targeting specific biological pathways.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or plant growth regulators where the coumarin-epoxide structure can impart specific bioactivity.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the production of specialty polymers, resins, and coatings, leveraging the reactivity of the epoxide ring.
• Fine Chemical Synthesis: Employed as a versatile precursor in organic synthesis for creating complex molecules in research and scale-up laboratories.
• Fluorescent Probe Development: Potential use in designing fluorescent markers or sensors, as the coumarin moiety is a well-known fluorophore.

Quality Control

Our 7-(Oxiranyloxy)-2H-1-Benzopyran-2-One is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific tests is provided with each shipment to support your quality assurance and regulatory needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
