| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| application | heptafluorobutyric anhydride can be used as an intermediate in pharmaceutical synthesis. High molecular weight carboxylic anhydrides such as substituted anhydrides and/or anhydrides containing more than 4 carbon atoms are usually prepared by contacting the corresponding carboxylic acid with acetic anhydride, for example, by contacting butyric acid with acetic anhydride. Sevobutyric anhydride can be prepared. |
| Uses | Derivative reagents and acylation reagents in gas chromatography. GC-MS derivatization reagent for analyzing the content of stereoisomers of synthetic peptides. GC derivatization reagent for the preparation of amino acids and other bioactive compounds? Hair derivatives |
