 Trifluoroacetic anhydride (CAS NO.407-25-0) may be prepared from trifluoroacetic acid by dehydrating with excess α-halogenated acid chlorides. For example, with dichloroacetyl chloride:
2 CF₃COOH + Cl₂CHCOCl → (CF₃CO)₂O + Cl₂CHCOOH + HCl

 Trifluoroacetic anhydride (CAS NO.407-25-0) hasn't been listed as a carcinogen by ACGIH, IARC, NTP, or CA Prop 65. And the toxicological properties have not been fully investigated. You can see actual entry in RTECS for complete information.

 Trifluoroacetic anhydride , its CAS NO. is 407-25-0,the synonyms is Aceticacid,trifluoro-,anhydride ; Anhydrid kyseliny trifluoroctove ; Anhydridkyselinytrifluoroctove ; Hexafluoroacetic anhydride ; Hexafluoroaceticanhydride ; Perfluoroacetic anhydride ; Perfluoroaceticanhydride ; Trifluoroacetic . In addition, Trifluoroacetic anhydride (CAS NO.407-25-0) could be stable under normal temperatures and pressures, and it absorbs moisture or water from the air. It is not compatible with water, metals, strong oxidizing agents, strong acids, strong bases, alcohols, alkali metals. And also prevent it to broken down into hazardous decomposition products: carbon monoxide, carbon dioxide, hydrogen fluoride gas, fluorine. It will not occur hazardous polymerization.
