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.

4-Methoxybenzene-1,3-diamine sulfate (4MBD) is a chemical substance that inhibits the activity of cytochrome P450 enzymes. It has been shown to inhibit the activity of rat liver microsomal p-450 enzymes, and is used in studies on the effects of chemicals on protein synthesis. When 4MBD is administered to rats at dietary concentrations, it causes an increase in thyroid hormone levels and a decrease in renal function. The enzyme inhibition caused by 4MBD may be due to its ability to acylate amines, which are located near the active site of the enzyme. Linear regression analysis showed that there was a strong correlation between dietary concentrations and the inhibition of protein synthesis caused by 4MBD.

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.
