Description

2,3-Oxiranedicarbonyl Dichloride (9Ci) is a highly reactive and versatile epoxide derivative used as a key synthetic intermediate. Its value lies in its bifunctional nature, featuring both an oxirane ring and acid chloride groups, enabling it to act as a cross-linking agent and building block for more complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries, where it facilitates the development of novel active ingredients and advanced materials. Its precise reactivity profile makes it a critical component in targeted synthesis and material science applications.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring epoxide or ester linkages.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators that incorporate reactive epoxide functionalities.
• Polymer Cross-Linking Agent: Acts as a reactive monomer or cross-linker in the manufacture of specialty epoxy resins, coatings, and adhesives with enhanced thermal and chemical resistance.
• Chemical Research & Development: A valuable reagent in organic synthesis for constructing heterocyclic compounds, dendrimers, and other complex molecular structures in R&D laboratories.
• Surface Modification: Employed to functionalize surfaces of materials (e.g., silica, polymers) by introducing reactive epoxide groups for further chemical attachment.
• Ligand and Catalyst Preparation: Used in the synthesis of specialized ligands and catalysts for asymmetric synthesis and other catalytic processes.

Quality Control

Our 2,3-Oxiranedicarbonyl Dichloride is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay (by titration or HPLC), identity confirmation (IR, NMR), and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. Our quality system is designed to support cGMP and ISO standards for advanced chemical intermediates, ensuring the material meets the exacting requirements of our global customer base in regulated industries.

Storage

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