Description

Oxirane, 2-Bromo-2-Ethynyl- (9Ci) is a highly reactive and versatile epoxide building block, valued for its unique combination of a bromine substituent and an ethynyl group on the oxirane ring. This molecular architecture makes it a critical intermediate for synthesizing complex molecules in advanced research and fine chemical production. It is primarily sought after by R&D chemists and process development teams in the pharmaceutical, agrochemical, and specialty polymer industries for constructing novel molecular scaffolds.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the development of novel active pharmaceutical ingredients (APIs), particularly in medicinal chemistry research targeting new therapeutic agents.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where its reactive groups allow for the introduction of specific bioactive moieties.
• Polymer & Material Science: Acts as a functional monomer or cross-linking agent in the development of specialty polymers, resins, and advanced materials with tailored properties.
• Organic Synthesis Building Block: Employed in academic and industrial R&D for constructing complex organic molecules, leveraging its epoxide ring for ring-opening reactions and its ethynyl group for click chemistry or further functionalization.
• Ligand & Catalyst Development: Utilized in the synthesis of specialized ligands and organometallic complexes for catalytic applications.

Quality Control

Our Oxirane, 2-Bromo-2-Ethynyl- (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by GC or HPLC), identity confirmation (by IR/NMR), and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area, ideally at 2-8°C or as specified on the label or COA. Due to its highly volatile and light-sensitive nature, containers should be kept sealed and allowed to reach ambient temperature before opening to minimize moisture ingress and degradation. Keep away from heat, sparks, and open flame.
