2-(2-Ethylphenyl)acetic acid is a compound that is used to synthesize antihistamines. It has been shown to have potent antihistaminic activity in both the ileum and the stomach, which is stereoselective for the S(+) enantiomer. The 2-ethylphenyl group of this compound can be susceptible to alkylation by organometallic reagents such as piperidine, which can lead to side reactions with other groups on the molecule or other molecules in the reaction mixture. The 2-ethylphenyl group is also chiral, meaning that it has two different forms, or configurations.

N-Benzyl-2-hydroxyacetamide is a synthetic molecule that is used in the synthesis of other molecules. It is synthesized by reacting benzaldehyde with 2-aminoethanol in the presence of hydrochloric acid and sodium hydroxide. The yields are typically high, as the reaction proceeds under relatively mild conditions with few side reactions. The mechanism of this reaction is nucleophilic addition of the amino group to the carbonyl carbon atom, followed by elimination of water. N-Benzyl-2-hydroxyacetamide can be converted to various other compounds through intramolecular reactions or substitutions on its molecular structure.

Benzo[b]thiophen-5-ol is a chiral molecule that has been synthesized to be homochiral. It has an active site and selective epoxide hydration activity, which is the rate-limiting step of epoxide ring opening reactions. The mechanism of this reaction is the cleavage of a C–C bond in an epoxide substrate by an O–H or S–H bond in benzo[b]thiophen-5-ol. The nature of this mechanistic bond cleavage reaction is unknown, but it may be due to catalysis by a benzyl group.

(E)-4-Bromo-N'-hydroxybenzimidamide is a synthetic antifungal agent that is resistant to many microorganisms. It is a potent inhibitor of the uptake of β-amyloid peptide in rat cortical neurons and also inhibits the modification of β-amyloid. This drug has been shown to have pharmacological effects on bacterial cells, including inhibition of protein synthesis and DNA synthesis. The molecular basis for these interactions is not known, but it has been suggested that (E)-4-Bromo-N'-hydroxybenzimidamide interacts with the pharmacophore site on bacteria and binds to nitrogen atoms that are important for binding. These interactions are bioisosteric with oxadiazole derivatives such as clotrimazole, which have been shown to inhibit protein synthesis in fungi. The drug has also been used as a radiotracer to study the uptake of β-amyloid peptides by neurons

3-formylpyridine-2-carboxylic acid is a phenylhydrazine derivative, which is a white crystalline solid. It is soluble in solvents such as chloroform and methanol, but insoluble in water. 3-Formylpyridine-2-carboxylic acid can be prepared by the chlorination of pyridine or by alkaline hydrolysis of its esters with sodium hydroxide. It can also be synthesized from the reaction of phenylhydrazine with formaldehyde in organic solvents. 3-Formylpyridine-2-carboxylic acid has been shown to react with carbonyl compounds to form a conjugated system through an addition reaction and to form esters that are soluble in organic solvents. The yield of this reaction depends on the solvent used and the temperature at which it is carried out.
