Description

5,5'-(Pyrimidine-2,5-Diyl)Diisophthalic Acid is a high-purity, multifunctional organic building block featuring a rigid pyrimidine core symmetrically linked to two isophthalic acid groups. This compound matters for its role as a key precursor in the synthesis of advanced materials, particularly metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), where its geometry and multiple coordination sites are critical. It is primarily needed by R&D chemists and material scientists in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel polymers, ligands, and porous network structures with tailored properties.

Application

• Metal-Organic Framework (MOF) Synthesis: Serves as a versatile organic linker for constructing porous, crystalline materials with applications in gas storage, separation, and catalysis.
• Covalent Organic Framework (COF) Precursor: Used as a monomer to build highly stable, porous organic polymers for sensing and optoelectronic devices.
• Pharmaceutical Intermediate: Acts as a sophisticated building block in the synthesis of complex drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Research: Employed in developing novel herbicides, fungicides, or plant growth regulators requiring specific pyrimidine-based architectures.
• Polymer Chemistry: Functions as a monomer or cross-linking agent to create high-performance polyamides, polyimides, or other specialty polymers with enhanced thermal and mechanical properties.
• Ligand Synthesis for Catalysis: Used to prepare multidentate ligands for transition metal complexes in homogeneous catalysis.
• Academic & Industrial R&D: A valuable tool for exploratory research in supramolecular chemistry and advanced material science.

Quality Control

Our 5,5'-(Pyrimidine-2,5-Diyl)Diisophthalic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider using a desiccator or inert atmosphere to maintain product integrity.
