Application:	Learn more in the Product Information
General description:	Heptafluorobutyric anhydride is a perfluoroacylated acylation reagent, that forms stable, volatile derivatives with alcohols, amines, and phenols. It is majorly used to prepare electron-capturing derivatives for GC/electron capture detection. It is generally used with an acid scavenger, to help drive the reaction to completion and to prevent column damage from acidic by-products of the derivatization reaction. It is also used for the frequent testing of drugs of abuse such as, amphetamines and phencyclidine by GC-MS technique.
Legal Information:	LiChropur is a trademark of Merck KGaA, Darmstadt, Germany
Other Notes:	HFAA acylates amines, amino acids and other compounds. HFBA derivatives are highly volatile: used in GC separation
Other Notes:	Reagent for 3-enol heptafluorobutyrate, heptafluorobutyrate, heptafluorobutyryl, 17-heptafluorobutyryl and 17-heptafluorobutyrate.
Packaging:	Clear borosilicate glass, high hydrolytic resistance (Type I)
