Description

Benzenepentacarboxylic Acid CAS NO 1585-40-6 is a high-purity, multi-functional aromatic carboxylic acid characterized by its five carboxyl groups attached to a benzene ring. This unique polyacidic structure makes it a valuable and versatile intermediate for synthesizing complex polymers, metal-organic frameworks (MOFs), and specialty chelating agents. It is essential for advanced material scientists and chemical engineers in industries such as polymer research, nanotechnology, and specialty chemical manufacturing.

Application

• Polymer Synthesis: A key monomer for producing high-performance polyamides, polyimides, and polyester resins with enhanced thermal stability and mechanical properties.
• Metal-Organic Frameworks (MOFs): Serves as a multi-dentate organic linker for constructing porous MOF materials used in gas storage, separation, and catalysis.
• Chelating Agents & Complexants: Used in the formulation of specialty chelating agents for water treatment, metal ion sequestration, and analytical chemistry.
• Pharmaceutical Intermediates: An important building block in the research and development of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Cross-linking Agent: Employed in coatings, adhesives, and epoxy resin systems to improve cross-link density and material performance.
• Research & Development: A critical reagent in academic and industrial R&D for exploring new organic synthesis pathways and functional materials.
