Diethoxy-methyl-thioxo-phosphorane is a chemical compound that is used in the manufacture of industrial chemicals. It has a vapor pressure of 0.0014 mmHg at 25°C, and can be quantified by chemical ionization with gas chromatography/mass spectrometry. Diethoxy-methyl-thioxo-phosphorane reacts with radiation to produce reactive oxygen species and other free radicals, which can damage DNA and cause cancer. The reaction rate is rapid, with an analogy to humans being exposed to nitrate compounds. Diethoxy-methyl-thioxo-phosphorane is also used in devices such as radiators and heaters, where it causes damage when combined with nitrates.

3-Fluoro-4-methoxybenzoic acid is a dipolar molecule with a fluorine atom. It has been synthesized experimentally and the yields are determined by the experimental conditions. 3-Fluoro-4-methoxybenzoic acid has two isomers, which can be differentiated by their resonances. The molecule also has an asymmetric C3(CF)2Cl group in the middle of its structure that can rotate freely.
