Description

1,2,4,5-Benzene Tetracarboxaldehyde is a high-purity, multifunctional aromatic aldehyde building block of significant interest in advanced organic synthesis. Its unique structure, featuring four reactive aldehyde groups symmetrically arranged on a benzene ring, makes it a critical precursor for constructing complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries seeking to develop novel polymers, macrocycles, and functional ligands.

Application

• Pharmaceutical Intermediate: Serves as a key starting material for the synthesis of complex drug candidates, particularly those requiring symmetrical, multi-functional scaffolds.
• Polymer & Resin Synthesis: Used as a cross-linking agent or monomer for producing high-performance polymers, thermosetting resins, and porous organic frameworks (POFs).
• Ligand & Chelator Production: Acts as a precursor for synthesizing sophisticated polydentate ligands and chelating agents used in catalysis and metal ion sequestration.
• Macrocyclic Compound Construction: Fundamental building block for creating crown ethers, cryptands, and other macrocyclic structures with specific host-guest properties.
• Agrochemical Synthesis: Employed in the development of novel active ingredients requiring a symmetrical, multi-reactive core.
• Advanced Material Research: Utilized in the development of organic electronic materials, sensors, and covalent organic frameworks (COFs) due to its ability to form extended networks.

Quality Control

Our 1,2,4,5-Benzene Tetracarboxaldehyde is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity, the material should be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and handled in a moisture-controlled environment.
