Description

1,3-Diisopropylimidazolium Hydrogencarbonate (Contains Varying Amounts Of 1,3-Diisopropylimidazolium-2-Carboxylate) is a high-purity, specialty ionic liquid salt that serves as a versatile precursor and catalyst in advanced organic synthesis. This compound is valued for its role as a CO2-adduct, functioning as a masked form of a stable N-heterocyclic carbene (NHC) for applications requiring controlled reactivity. It is primarily sought by R&D and production chemists in the pharmaceutical, agrochemical, and fine chemical industries for processes including asymmetric catalysis, polymerization initiators, and the synthesis of complex molecular architectures.

Application

• Organocatalysis: Acts as a precursor to generate in-situ N-heterocyclic carbenes (NHCs) for benzoin condensations, transesterification, and other C-C bond-forming reactions.
• Pharmaceutical Intermediate Synthesis: Utilized in the development and scalable production of active pharmaceutical ingredients (APIs) requiring precise stereochemical control.
• Polymer Science: Serves as an initiator or catalyst in ring-opening polymerization (ROP) to produce biodegradable polyesters and other specialty polymers.
• Agrochemical Manufacturing: Employed in the synthesis of advanced herbicides, fungicides, and plant growth regulators.
• Ligand and Complex Preparation: Used to synthesize NHC-metal complexes for homogeneous catalysis, including cross-coupling and hydrogenation reactions.
• CO2 Capture and Utilization (CCU): Functions as a model compound or component in research focused on reversible CO2 absorption and chemical fixation processes.
• Ionic Liquid Research: Provides a tunable cation for developing novel ionic liquid matrices with specific solvation properties for electrochemistry or separation technologies.
