Description

1,3,5-Tris(4-Phosphonophenyl)Benzene is a high-purity, multi-functional organophosphorus compound characterized by its rigid, symmetrical aromatic core. This structure is critical for applications requiring strong metal chelation, thermal stability, and the ability to form robust coordination networks. It serves as a key advanced intermediate for researchers and manufacturers in high-performance material science and specialty chemical synthesis. Target industries include those developing flame retardants, metal-organic frameworks (MOFs), corrosion inhibitors, and novel catalysts.

Application

As a precursor or ligand in the synthesis of Metal-Organic Frameworks (MOFs) and coordination polymers for gas storage, separation, and catalysis.
As a chelating agent and corrosion inhibitor in advanced water treatment formulations and protective coatings for metals.
As a reactive monomer or additive in the production of flame-retardant polymers and high-temperature resins.
In the development of heterogeneous catalysts for organic synthesis and industrial chemical processes.
As a building block for functional materials used in sensors, proton-conducting membranes, and electronic devices.
For academic and industrial R&D in supramolecular chemistry and material science.

Quality Control

Our 1,3,5-Tris(4-Phosphonophenyl)Benzene is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Standard quality parameters include assay/purity, identity confirmation, and control of key impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with relevant research and industrial standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under dry, inert conditions (e.g., nitrogen or argon atmosphere) for long-term storage to prevent degradation. Recommended storage temperature: 2-8°C for extended stability.
