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.

3-Amino-4-fluorobenzoic acid is a hydrocarbon that is used as an analgesic. It has been shown to be nontoxic and has analgesic effects in the intestinal tract. 3-Amino-4-fluorobenzoic acid also has radiopaque properties, which makes it useful for diagnosis and treatment of certain types of cancer and other tumors. The analgesic effect of 3-amino-4-fluorobenzoic acid may be due to its ability to act as a competitive antagonist at the N -methyl--aspartate (NMDA) receptor, which is important in pain perception.

Potassium bis(fluorosulfonyl)imide (K2FSI) is a reactive chemical that can be used to remove sulfur from petroleum products. It is also used in the manufacturing of ethylene and perovskite solar cells. K2FSI reacts with potassium ions to form potassium hexafluorophosphate (KHF2). This reaction reduces the vapor pressure of KHF2 and increases its solubility in water. The use of K2FSI can reduce the amount of energy needed for desulfurization, as it does not require heating. The following are some uses for potassium bis(fluorosulfonyl)imide: - As a catalyst for production of ethylene - In organic solvent to produce perovskite solar cells - To remove sulfur from petroleum products - To make hydrogen fluoride - For desulfurization
