Description

Trichloroboroxin CAS NO 13703-91-8 is a specialized organoboron compound primarily used as a versatile reagent and intermediate in advanced chemical synthesis. Its significance lies in its role as a precursor for generating other boron-containing compounds and as a catalyst or co-catalyst in various polymerization and cross-linking reactions. This product is essential for R&D laboratories and industrial manufacturers in the fields of polymer chemistry, materials science, and the production of high-performance ceramics and flame retardants.

Application

• Polymerization Catalyst/Co-catalyst: Used in the synthesis of specialty polymers, including silicones and epoxy resins, to control molecular weight and cross-linking density.
• Ceramic Precursor: Serves as a key starting material in the production of boron nitride (BN) and other advanced ceramic materials via chemical vapor deposition (CVD) or sol-gel processes.
• Flame Retardant Synergist: Acts as an intermediate in the manufacture of halogenated flame retardant systems for plastics and textiles.
• Organic Synthesis Reagent: Employed as a Lewis acid catalyst in Friedel-Crafts alkylation, acylation, and other condensation reactions.
• Surface Modification Agent: Used to functionalize surfaces of inorganic materials like silica or metals to improve adhesion and compatibility in composite materials.
• Cross-linking Agent: Facilitates the formation of three-dimensional networks in silicone rubbers and other elastomers to enhance thermal and mechanical properties.

Quality Control

Our Trichloroboroxin is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including NMR, FT-IR, and titration methods. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, chloride content, and moisture levels to meet your specific application 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) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and organic solvents.
