5-Chloro-2-fluorobenzaldehyde is an efficient method for synthesizing substituted benzoic acid derivatives. It is a useful reagent in the acylation reaction. 5-Chloro-2-fluorobenzaldehyde also has high yields and can be used as a substitute for other more toxic or expensive compounds.

1-Ethyl-3-methyl-1H-pyrazole-4-carbaldehyde is a reactive intermediate that is used as a reagent in organic synthesis. It is also a useful scaffold for the synthesis of complex compounds, such as pharmaceuticals and agrochemicals. 1-Ethyl-3-methyl-1H-pyrazole-4-carbaldehyde has been used as an intermediate to synthesize the antihistamine drug terfenadine and the insecticide carbofuran. This chemical is manufactured by reacting ethyl pyruvate with anhydrous hydrazine.

3-Ethynylbenzaldehyde is a tryptic, nitro compound that contains terminal alkynes and has functional groups. The functional theory of this compound suggests that it may be used as a chemosensor for the detection of acidic compounds. 3-Ethynylbenzaldehyde reacts with sodium trifluoroacetate to form an aldehyde, which is then oxidized to an acid by the addition of water. This acid can be detected using NMR spectroscopy. 3-Ethynylbenzaldehyde has been shown to react with sodium trifluoroacetate in solid form at room temperature and above. The resulting product is a yellow crystalline solid that can be identified by its UV spectrum.

3-Butoxybenzaldehyde is an electron donor. It is used in the synthesis of heterocyclic compounds and as a reagent or postulated intermediate in the formation of epoxides, ethylene, and peroxides. 3-Butoxybenzaldehyde also functions as a precursor to other oxygenated compounds. 3-Butoxybenzaldehyde has been shown to undergo both aldol condensation and interaction with other compounds.
