On the submission form accompanying this sample, submitter indicated this was sold as ''4-FA (F-fluoroamphetamine)''.
Mar 28 2024: The two previously unidentified substances have been identified as isomers of N-(1-(4-fluorophenyl)prop-1-en-2-yl)hydroxylamine, byproducts of the ''artisanal'' synthesis of fluoroamphetamine, presumably ''using fluorobenzaldehyde contaminated with benzaldehyde [via] reduction with concentrated acetic acid with zinc...,'' in the words of a consulting Erowid Expert Network chemist. (Thank you, Y. and Borax)

Mar 27 2024: Originally, in the lab, Unidentified #1 and Unidentified #2 appear to be the same compound, double peak.
Regarding positional isomers: Two chemicals in this sample have multiple 'ring-positional isomers'. That means that the hexagonal benzene ring that makes up part of the chemical can have 'arms' that form the rest of the chemical attached at various locations around the ring. Some chemicals, such as these, have multiple possible places along the ring that these parts can attach, and have nearly-identical or identical retention times in the Gas Chromatograph (GC) and identical mass spectra (MS).

This sample contains Fluoroamphetamine and N-acetyl Fluoroamphetamine, but at this time we can't be certain which positional isomer(s).
