Methyl 3-chloropropionate is an alkyl ether that has been used in clinical studies as a liquid phase ion-pair extraction solvent. It was developed to replace the use of hexane, which is not environmentally friendly and can also cause irritation. Methyl 3-chloropropionate has been shown to have a higher viscosity than hexane at room temperature and is less likely to evaporate than hexane. Methyl 3-chloropropionate has also been used as a synthetic process solvent, with the reaction time being shorter than that of hexane. This compound can be used for chromatography without any effect on the solute or the stationary phase. Methyl 3-chloropropionate has also been shown to be effective in lipase and agarose gel assays, as well as chloride ion extraction from water samples.

2,5-Diethoxyterephthalohydrazide is an organic compound that has been used for the synthesis of linkers with various functional groups.

2,4,6-Triphenylpyridine is an aromatic heterocycle with a benzyl group and trifluoroacetic acid at the 2-, 4-, and 6-positions. It is a colorless solid that has a melting point of 183 °C. In the gas phase, it exists as three anion radicals (2-, 4-, and 6-). These radicals are responsible for its optical properties. The 2-anion radical has a blue emission spectrum while the 4- and 6-anion radicals have red emission spectra. 2,4,6-Triphenylpyridine can be used as an indicator for trifluoroacetic acid or benzonitrile. It is soluble in primary alcohols such as methanol and ethanol at lower temperatures, but becomes insoluble at higher temperatures. 2,4,6-Triphenylpyridine also has functional theory applications due to its ability to
