Description

Copper, [1,3-Bis[2,6-Bis(1-Methylethyl)Phenyl]-2-Imidazolidinylidene]Chloro- is a highly specialized N-heterocyclic carbene (NHC) copper(I) complex, valued for its exceptional stability and catalytic activity. This organometallic compound serves as a versatile and efficient catalyst for a wide range of cross-coupling and organic transformation reactions. It is primarily sought by pharmaceutical intermediates, advanced material synthesis, and specialty chemical R&D sectors for constructing complex molecular architectures.

Application

• Catalyst for C-N, C-O, and C-C cross-coupling reactions (e.g., Buchwald-Hartwig amination, Ullmann-type couplings).
• Key reagent in pharmaceutical intermediate synthesis, enabling the formation of challenging bonds under mild conditions.
• Precursor for materials science applications, including the deposition of copper films and the synthesis of conductive polymers.
• Ligand transfer agent in the preparation of other metal-NHC complexes for catalytic studies.
• Research chemical for developing new methodologies in organic and organometallic chemistry.
• Polymerization catalyst for specific ring-opening and coordination-insertion polymerizations.

Quality Control

Our high-purity organometallic catalysts are manufactured and handled under controlled environments to ensure batch-to-batch consistency and optimal catalytic performance. Each lot undergoes rigorous analytical testing, including NMR, elemental analysis (EA), and HPLC, to verify identity, purity, and the absence of deleterious impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C to prevent oxidation and decomposition. The container should be kept in a cool, dry, and well-ventilated place, away from incompatible materials.
