Chemical Identity and Properties

Tributyl(methyl)phosphonium Dimethyl Phosphate (Aladdin SKU: T405120; TCI reference T3945) is a quaternary phosphonium salt belonging to the ionic liquid family. It consists of a tributyl(methyl)phosphonium cation paired with a dimethyl phosphate anion. As a room-temperature ionic liquid, it exhibits negligible vapour pressure under standard ambient conditions, distinguishing it from conventional volatile organic solvents. Its organophosphorus backbone imparts tuneable solvation properties relevant to dissolution, extraction, and catalytic applications. Researchers should consult the supplier's Safety Data Sheet (SDS) for precise physicochemical data, including exact melting point, density, and viscosity, as these values are subject to batch-specific confirmation.

Handling and Safety Guidelines

Although ionic liquids are generally considered low-volatility alternatives to organic solvents, appropriate laboratory precautions remain mandatory when working with Tributyl(methyl)phosphonium Dimethyl Phosphate. Personnel should wear chemical-resistant gloves, safety goggles, and a laboratory coat at all times. Work should be conducted in a well-ventilated fume hood, especially during heating or large-scale operations. Avoid contact with skin, eyes, and mucous membranes. In the event of skin contact, wash the affected area thoroughly with soap and water. In the event of eye contact, irrigate immediately with copious amounts of water and seek medical attention. The compound should be stored in a tightly sealed container in a cool, dry area away from strong oxidisers and moisture. Dispose of waste material in accordance with local and institutional regulations governing phosphorus-containing compounds. Always refer to the current SDS provided by Aladdin Scientific for authoritative hazard classifications and first-aid measures.

Research Applications

Tributyl(methyl)phosphonium Dimethyl Phosphate finds utility across several research domains owing to the characteristic properties of phosphonium-based ionic liquids. Key application areas include: Organophosphorus chemistry — serving as a reagent or reaction medium in the synthesis and study of phosphorus-containing molecules; Phase-transfer catalysis — quaternary phosphonium salts are established phase-transfer catalysts that facilitate reactions between reagents located in immiscible phases; Ionic liquid research — as a member of the ionic liquid class, it may be evaluated for its solvation, electrochemical, or thermal properties in fundamental studies; Dissolution and extraction — ionic liquids with phosphonium cations have been investigated for dissolving biopolymers and extracting metal ions. Researchers are encouraged to review primary literature for specific reaction conditions and performance data relevant to their application, as optimised protocols will vary by experimental context.

Storage, Stability, and Quality Considerations

Proper storage is essential to maintain the integrity and performance of Tributyl(methyl)phosphonium Dimethyl Phosphate. The compound should be kept in its original, tightly closed container under cool and dry conditions. Exposure to atmospheric moisture may affect product quality; therefore, handling under inert atmosphere (e.g., nitrogen or argon) is advisable when rigorous anhydrous conditions are required. Avoid prolonged exposure to light or elevated temperatures. Upon receipt, inspect the product for visual abnormalities. If the material does not meet specification, contact Aladdin Scientific's technical support team. For procurement and specification queries, refer to the product listing under SKU T405120 on the Aladdin Scientific catalogue. Lot-specific certificates of analysis (CoA) are available upon request and should be retained for documentation and regulatory compliance purposes.
