Description

Tri-tert-Butylphosphonium Tetraphenylborate is a high-purity, non-coordinating phosphonium salt primarily used as a versatile catalyst and reagent in advanced organic synthesis. Its value lies in providing a stable, bulky phosphonium cation paired with a non-nucleophilic tetraphenylborate anion, enabling precise control in polymerization and coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking efficient and selective catalytic systems.

Application

• As a catalyst or co-catalyst in olefin polymerization and other transition metal-catalyzed reactions.
• As a phase-transfer catalyst (PTC) for facilitating reactions between immiscible phases in organic synthesis.
• As a precursor or reagent in the synthesis of specialized ionic liquids and other functional materials.
• In the preparation of organometallic complexes where a non-coordinating counterion is required.
• For academic and industrial R&D in novel catalytic processes and material science.
• As a stabilizing agent or additive in advanced polymer formulations and electronic materials.

Quality Control

Our Tri-tert-Butylphosphonium Tetraphenylborate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high chemical purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request 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 place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
