1-Bromo-3-ethylbenzene (1BEB) is a trifluoroacetic acid that is used as a reagent in the analysis of urine samples. It reacts with glutathione to form a fluorescent product, which can be detected by fluorescence spectroscopy. 1BEB reacts with methyl groups in the sample to produce an intermediate compound that can be measured by liquid chromatography-mass spectrometry (LC/MS). The reaction time for this process depends on the temperature and other conditions such as pH. LC/MS has been shown to be more accurate than kinetic measurements for the determination of 1BEB concentrations in urine because it takes into account the chemical reactions that take place during the analysis. In addition, methylbenzenes are also formed during this process, which can be analysed using gas chromatography-mass spectrometry (GC/MS). GC/MS has been shown to be more accurate than LC/MS methods for evaluating

Terephthalaldehyde chloride is a water-insoluble, white solid that is soluble in organic solvents. It forms a protective layer on metal surfaces and plastics, preventing corrosion and microbial growth. Terephthalaldehyde chloride has been shown to be effective against Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, and Salmonella enterica. Terephthalaldehyde chloride's antimicrobial activity is attributed to its acid complex with phosphorus pentoxide and electrochemical impedance spectroscopy data indicate that it reacts with the anionic sites of bacterial cell walls. Terephthalaldehyde chloride does not react with human serum proteins or ester linkages; however, it has toxic effects on mice at high doses.

3,4-Methylenedioxy amphetamine hydrochloride is an enantiomer of methylenedioxyamphetamine. It is a synthetic molecule that has been used as a drug and chemical intermediate. 3,4-MDA has not been detected in any natural products. 3,4-MDA is not soluble in water but is soluble in most organic solvents and oils. 3,4-MDA can be made into a non-polymeric form by adding acid to the molecule. The impurities are typically related to the solvent used during synthesis and include unreacted starting materials, side products from chemical reactions, and traces of other chemicals such as acetyl derivatives or polymers. 3,4-MDA can be assayed using high performance liquid chromatography (HPLC) with fluorescent detection; however, due to the impurities present in this substance it may be difficult to obtain a reliable result. There are two polymorphs for 3,4-MDA:

3-(1-Piperidin-1-ylcyclohexyl)phenyl]amine hydrochloride is a ligand that binds to the acetylcholine receptor. 3-(1-Piperidin-1-ylcyclohexyl)phenyl]amine hydrochloride is an active analogue and has a high binding affinity for the cholinergic receptor. It has been shown to have a kinetic effect on the excitatory system, enhancing excitatory effects of acetylcholine without affecting inhibitory effects. 3-(1-Piperidin-1-ylcyclohexyl)phenyl]amine hydrochloride also has an antagonistic effect on modifiers of acetylcholine activity such as amantadine, but enhances the effects of other drugs, such as clonidine.
