Description General description Heptafluorobutyric anhydride (HFB) is a derivatizing reagent. It provides facile and sensitive way for detecting and elucidating structure of numerous alkyl-chain homologs. Application GC derivatizing agent used to prepare volatile derivatives of amino acids and other biologically active compounds. HFB was used as derivatizing agent in analysing platelet-activating factor using GC-MS. Packaging 10×1, 5, 25 mL in ampule Derivatization reagent used in a GC-MS analysis of stereoisomer content of synthetic peptides. Other Notes Reagent for heptafluorobutyrate, 3-enol heptafluorobutyrate, 17-heptafluorobutyrate, heptafluorobutyrate and heptafluorobutyryl.
