Task: Please give me a SMILES based on the text description below.
Description: The molecule is an acyclic carboxylic anhydride that is perfluorinated butyric anhydride. It is used as a derivatising reagent for gas chromatographic analyses. It has a role as a chromatographic reagent. It is an organofluorine compound and an acyclic carboxylic anhydride. It derives from a butyric acid.
Result: O=C(OC(=O)C(F)(F)C(F)(F)C(F)(F)F)C(F)(F)C(F)(F)C(F)(F)F
