Description

Iodonium, Bis[4-(Trifluoromethyl)Phenyl]-, 1,1,1-Trifluoromethanesulfonate (1:1) is a high-purity diaryliodonium salt, a critical class of photoacid generators (PAGs) and versatile arylating agents. This compound matters for its exceptional reactivity and stability, enabling precise control in advanced material synthesis and photopolymerization processes. It is primarily needed by R&D chemists and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures and developing next-generation photoresists.

Application

• Photoacid Generator (PAG) for Advanced Photoresists: A key component in chemically amplified resists (CARs) for deep-UV (DUV) and extreme-UV (EUV) lithography in semiconductor manufacturing.
• Aryl Cation Source for C-H Functionalization: Enables direct arylation of arenes and heteroarenes under mild conditions for pharmaceutical intermediate synthesis.
• Catalyst/Initiator for Cationic Polymerization: Used to initiate the ring-opening polymerization of epoxides, oxetanes, and vinyl ethers for coatings, adhesives, and composites.
• Electrophilic Arylating Agent: For the introduction of the 4-(trifluoromethyl)phenyl group into nucleophiles like enolates, amines, and thiols.
• Reagent in Organic Synthesis: Facilitates cross-coupling reactions and the synthesis of complex natural product analogs and agrochemicals.
• Surface Modification Agent: Used to functionalize material surfaces with fluorinated aryl groups to alter hydrophobicity and chemical resistance.

Quality Control

Our Iodonium, Bis[4-(Trifluoromethyl)Phenyl]-, 1,1,1-Trifluoromethanesulfonate (1:1) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and KF titration for moisture content, to ensure it meets exacting R&D and production specifications. Certificates of Analysis (COA) with full traceability are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as specified on the label. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when opening to prevent degradation. Keep away from strong bases and reducing agents.
