General description

Carbon tetrafluoride (CF4), also known as tetrafluoromethane, belongs to the class of fluoromethanes. It can be prepared by the reaction of silicon carbide with fluorine. It is used as a refrigerant.[1][2]

Application

Carbon tetrafluoride can be used in fluorine chemistry for the preparation of organofluorine compounds. It is also used as a solvent in low-temperature reactions [1]. During the manufacture of electronics devices, CF4 plasma is widely used to etch a variety of materials.[3]

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

Compatible with the following:
  • Aldrich® lecture-bottle station systems
  • Aldrich® lecture-bottle gas regulators

Evans-type chiral lithium imide enolates undergo diastereoselective α-trifluoromethylation with a hypervalent iodine-CF(3) reagent with up to 91% combined isolated yield and 97:3 dr. The resulting isolated diastereopure products can be further transformed into valuable products without racemization.

The inflammatory cell response of tetrafluorocarbon (CF4) plasma surface modification of poly(methyl methacrylate) intraocular lenses (IOLs) was investigated in vitro. After two hours of lens contact with human granulocytes, scanning electron microscopy showed significantly less cell activation and granulocyte adhesion
