Description

2,3-Oxiranedicarbonyl Dichloride, (2R,3S)-Rel- (9Ci) is a high-purity, stereochemically defined chiral building block of significant synthetic utility. This compound matters as a versatile electrophilic intermediate for introducing functionalized epoxide moieties into target molecules, enabling the synthesis of complex, optically active structures. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the development of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of protease inhibitors, kinase inhibitors, and other biologically active molecules requiring specific stereochemistry.
• Agrochemical Synthesis: Used in the research and development of advanced, stereoselective herbicides, fungicides, and insecticides.
• Ligand and Catalyst Preparation: Serves as a precursor for creating chiral ligands and organocatalysts used in asymmetric synthesis.
• Polymer Modification: Employed to introduce reactive epoxide groups into polymer backbones for cross-linking or further functionalization.
• Academic & Contract Research: Essential for methodological development in organic chemistry and for custom synthesis projects in CROs (Contract Research Organizations).
• Fine Chemical Production: Utilized in the multi-step synthesis of complex, high-value specialty chemicals and flavors/fragrances intermediates.

Quality Control

Our 2,3-Oxiranedicarbonyl Dichloride, (2R,3S)-Rel- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with exacting research and development standards. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided and available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
