The IUPAC name of Mercuric trifluoroacetate is mercury(2+); 2,2,2-trifluoroacetate . With the CAS registry number 13257-51-7, it is also named as Bis(trifluoroacetato)mercury ; Acetic acid, 2,2,2-trifluoro-, mercury salt (2:1) ; Mercury bis(trifluoroacetate) ; Mercury(II) trifluoroacetate . It is hygroscopic and can absorb moisture from the air. Mercuric trifluoroacetate is raw material of fine chemicals and pharmaceutical intermediates. So it can be used in the pharmaceutical synthesis. Both linear and cross-linked copolymers of N-vinylcarbazole and methylacrylate can be prepared and mercuriated by using mercury trifluoroacetate in THF or dichloromethane. The role of mercuric trifluoroacetate as reactive agent and activator in reactions of various Se-alkyl phosphoroselenoates with O- and N-nucleophiles is examined.
Mercuric trifluoroacetate is very toxic by inhalation, in contact with skin and if swallowed. It has danger of cumulative effects. It is also very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. So we must keep Mercuric trifluoroacetate away from food, drink and animal foodstuffs. After contact with skin, wash immediately with plenty of soap-suds. If you want contact with it, you must wear suitable protective clothing. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
The products indicated contain mercury. Don't put products containing mercury in the trash. So this material and its container must be disposed of as hazardous waste. Products containing mercury may be regulated by Local, State, or Federal Laws. Some products containing mercury are not available for sale in some states.
