Anwendungen

It is used as the reagent for the derivatization of amines, alcohols, etc., for GC purposes. It has been utilized for dual element acetylation tagging derivatization of amines by using microwave sustained helium emission detector1 and as a derivatization reagent in determination of estrone and 17β-estradiol in hair by GC-MS2.

Bemerkungen

Moisture sensitive. Handle under dry protective gas. Keep away from oxidizing agents, strong bases.
