Description

Benzene-1,3,5-Trisphosphonic Acid is a high-purity, multifunctional organic phosphonic acid derivative characterized by its symmetrical aromatic core and three phosphonic acid groups. This unique structure makes it a highly effective chelating agent and a versatile building block for advanced materials synthesis. It is essential for researchers and manufacturers in industries requiring precise metal ion control or the development of functional polymers and coatings. The compound is supplied under stringent quality control to ensure batch-to-batch consistency for critical applications.

Application

• Metal Chelation & Sequestration: Used in water treatment, industrial cleaning formulations, and as a scale inhibitor to control calcium, magnesium, and other metal ions.
• Pharmaceutical Intermediates: Serves as a key synthon for the development of novel active pharmaceutical ingredients (APIs) and diagnostic agents.
• Functional Polymers & Resins: Acts as a cross-linking agent or monomer for producing ion-exchange resins, flame-retardant materials, and specialty adhesives.
• Surface Treatment & Corrosion Inhibition: Applied in metal surface pretreatment and as an additive in cooling systems and anti-corrosion coatings.
• Catalysis & Ligand Synthesis: Employed in the preparation of homogeneous catalysts and complexing ligands for organic synthesis and material science.
• Nanomaterial Fabrication: Utilized as a stabilizing or functionalizing agent in the synthesis of metal-organic frameworks (MOFs) and other nanostructured materials.

Quality Control

Our Benzene-1,3,5-Trisphosphonic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and titration methods, to verify identity, purity, and consistency. Certificates of Analysis (COA) documenting all test results are provided and can be tailored to meet specific customer or regulatory requirements.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
