4-APC (hydrobromide)
4-APC hydrobromide is a highly sensitive and selective derivatization agent for aldehydes. 4-APC hydrobromide possesses an aniline moiety for a fast selective reaction with aliphatic aldehydes as well as a quaternary ammonium group for improved MS sensitivity. 4-APC hydrobromide allows highly sensitive and selective MS detection of aldehydes.
