(4-methylphenyl)-(4-propan-2-ylphenyl)iodanium;tetrakis(2,3,4,5,6-pentafluorophenyl)boranuide

(4-methylphenyl)-(4-propan-2-ylphenyl)iodanium;tetrakis(2,3,4,5,6-pentafluorophenyl)boranuide is an iodonium salt with the molecular formula C40H18BF20I and CAS number 178233-72-2. This complex organometallic compound features an iodonium cation paired with a fluorinated borate anion, resulting in a high molecular weight of 1016.3 g/mol. The substance is classified as hazardous with moderate toxicity and environmental concerns.

This iodonium salt is a solid compound with a high molecular weight of 1016.3 g/mol, containing multiple fluorinated aromatic rings. The presence of the perfluorinated borate anion contributes to its chemical stability and unique solubility characteristics. Due to its organometallic nature and fluorinated structure, it typically exhibits limited water solubility but may be soluble in organic solvents.

This iodonium salt is primarily used as a photoinitiator in advanced polymer chemistry and photolithography applications. The compound serves as a cationic photoinitiator, generating reactive species upon UV exposure to initiate polymerization reactions. It finds applications in specialty coatings, adhesives, and electronic materials manufacturing where precise photochemical control is required.

Safe handling requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Acute Tox. 4 classification. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin and eye contact, and ensure proper hygiene practices. The GHS07 and GHS08 pictograms indicate health hazards requiring careful handling procedures.

The compound should be stored in a cool, dry place away from direct light and heat sources, as it is light-sensitive due to its photoinitiator properties. Keep containers tightly sealed to prevent moisture absorption and contamination. Storage areas should be well-ventilated and equipped with appropriate spill containment measures. Avoid storage near incompatible materials and ensure proper labeling according to CLP requirements.

Immediate action is required upon contact due to its toxicity classification. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with plenty of clean water for at least 15 minutes. If inhaled, move to fresh air immediately. Seek medical attention if symptoms develop or persist, and provide safety data sheet information to medical personnel.

Disposal must comply with local and European waste regulations due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1). The substance cannot be disposed of through regular waste streams and requires treatment as hazardous chemical waste. Contact licensed waste disposal companies for proper collection and treatment. Never discharge into drains, soil, or water bodies due to its aquatic toxicity.

Transportation is regulated under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III, indicating moderate danger during transport. Packages must be properly labeled with appropriate hazard markings and accompanied by transport documentation. Use approved packaging materials and ensure compliance with international shipping regulations. Professional logistics providers experienced in chemical transport should handle shipment to ensure regulatory compliance.

The substance is subject to CLP regulation due to its hazard classification and requires appropriate labeling with Warning signal word and GHS pictograms. REACH registration requirements apply for importers and manufacturers. While not currently listed as SVHC, its environmental classification requires compliance with water protection legislation. Users must maintain safety data sheets and implement appropriate risk management measures.
