N-Ethyl-4-fluoroaniline Hydrochloride can be useful in the study of molecular rearrangement of oximes on reduction with lithium aluminum hydride. It is a salt analog of N-Ethyl-4-fluoroaniline (CAS# 405-67-4), which can be useful in the discovery of positive allosteric modulators of GluN2A-containing NMDARs and synthesis of antimalarial isoneocryptolepine analogs.
