Tributylmethylphosphonium methylsulfate, CAS: 69056-62-8

Key Applications:

This product has applications in the following:

1. Phase‑Transfer Catalysis (PTC)

• Enhances reaction rates in biphasic organic–aqueous systems
• Effective for nucleophilic substitutions, alkylations, and condensations
• Preferred in processes requiring higher thermal stability than ammonium analogs

2. Ionic‑Liquid Precursor & Solvent Component

• Used as a building block for designing task‑specific ionic liquids
• Contributes to high‑conductivity, low‑volatility solvent systems
• Supports electrochemical and extraction applications where phosphonium stability is advantageous

3. Polymer & Materials Processing

• Acts as a processing aid or compatibilizer in specialty polymer formulations
• Useful in modifying polymer polarity and improving dispersion of fillers
• Employed in ion‑conducting polymer matrices and membranes

4. Catalysis & Organic Synthesis

• Serves as a stable, non‑volatile medium for metal‑catalyzed transformations
• Supports high‑temperature or strongly basic reaction environments
• Used in esterifications, oxidations, and carbon–carbon bond‑forming reactions

5. Extraction & Separation Processes

• Functions as a hydrophilic ionic species for selective extraction of metal ions
• Applied in biphasic separation systems for green chemistry workflows
• Suitable for aqueous‑phase separations requiring thermal robustness

6. Antistatic & Surface‑Modification Additive

• Provides ionic conductivity in coatings, lubricants, and antistatic formulations
• Enhances charge dissipation in industrial and electronic materials
