Description

Tetrakis(Acetonitrile)Copper(I) Trifluoromethanesulfonate Hemihydrate is a high-purity, organometallic copper(I) complex widely used as a versatile catalyst and reagent in organic synthesis. Its primary value lies in its ability to facilitate key coupling and cycloaddition reactions under mild conditions, offering chemists a powerful tool for constructing complex molecular architectures. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors, where precise catalytic activity is paramount for developing new active ingredients and functional polymers.

Application

• Catalyst in Organic Synthesis: Employed as a highly effective catalyst for copper-catalyzed azide-alkyne cycloaddition (CuAAC) "click" chemistry, enabling rapid and reliable bioconjugation and polymer functionalization.
• Pharmaceutical Intermediate Manufacturing: Used in the synthesis of complex heterocycles and active pharmaceutical ingredients (APIs) through coupling reactions like Chan-Lam and Ullmann-type couplings.
• Agrochemical Research: Facilitates the development of novel herbicides and pesticides by enabling the construction of specific nitrogen-containing ring systems.
• Materials Science: Serves as a precursor or catalyst in the creation of conductive polymers, metal-organic frameworks (MOFs), and other advanced functional materials.
• Ligand Exchange Reactions: Acts as a soluble source of the Cu(I) cation in reactions where labile acetonitrile ligands can be displaced by other donor molecules.
• Academic & Industrial R&D: A staple reagent in research laboratories for methodological development in synthetic organic and organometallic chemistry.

Quality Control

Every batch of Tetrakis(Acetonitrile)Copper(I) Trifluoromethanesulfonate Hemihydrate is manufactured and tested under strict quality management protocols to ensure consistent purity and catalytic performance. Our standard material meets high-purity research-grade specifications, with comprehensive testing including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) detailing all quality parameters are provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry place. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air, moisture, or elevated temperatures will compromise stability and catalytic activity.
