Description

4-[Bis(2-Diphenylphosphanylethyl)Carbamoyl]Benzene-1,2-Dicarboxylic Acid is a sophisticated, multi-dentate ligand featuring a central phthalic acid core functionalized with a carbamoyl-linked bis(phosphine) moiety. This compound matters for its unique ability to chelate transition metals, forming highly stable and active complexes crucial for advanced catalytic processes. It is primarily needed by researchers and manufacturers in the fields of homogeneous catalysis, organometallic chemistry, and materials science.

Application

• Homogeneous Catalysis: As a key ligand for constructing transition metal catalysts used in cross-coupling reactions (e.g., Suzuki, Heck), hydrogenation, and hydroformylation.
• Organometallic Synthesis: For the preparation of novel metal-organic complexes with tailored electronic and steric properties for research and development.
• Polymerization Catalysts: In the development of Ziegler-Natta or metallocene-type catalysts for the production of specialty polymers and plastics.
• Pharmaceutical Intermediates: As a building block or catalyst component in the synthesis of complex, high-value active pharmaceutical ingredients (APIs).
• Materials Science: In the creation of metal-organic frameworks (MOFs) or coordination polymers with potential applications in gas storage, separation, or catalysis.
• Asymmetric Synthesis: Potential use in designing chiral catalysts for enantioselective transformations, critical for producing single-isomer compounds.

Quality Control

Our production of 4-[Bis(2-Diphenylphosphanylethyl)Carbamoyl]Benzene-1,2-Dicarboxylic Acid adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research and industrial applications. Each lot is characterized using advanced analytical techniques, including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from strong acids and incompatible materials. Due to its sensitivity, allow the container to reach room temperature before opening to minimize moisture ingress.
