Description

Oxirane, 2-(3,3-Dimethyl-1-Butynyl)-3-Ethenyl-, cis- (9Ci) is a specialized, high-value oxirane derivative featuring a unique combination of a terminal alkyne and an ethenyl group on the oxirane ring. This compound serves as a critical advanced chemical intermediate for synthesizing complex molecules, enabling the introduction of reactive epoxide and alkyne functionalities in a single step. It is primarily sought by pharmaceutical R&D and agrochemical laboratories for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting complex heterocycles.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where its reactive groups allow for structural diversification.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers and resins with tailored properties.
• Click Chemistry: The alkyne moiety makes it a valuable substrate for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, a cornerstone of bioconjugation and materials labeling.
• Ligand and Catalyst Development: Used to create sophisticated chiral ligands or metal-organic frameworks (MOFs) for asymmetric catalysis.
• Fine Chemical Production: Intermediate in the multi-step synthesis of flavors, fragrances, and other high-value specialty chemicals.
