It can be introduced into an aromatic compound from a diazonium salt via the Schiemann reaction rather than the Sandmeyer reaction, which is used for other elements in its group.

Inorganic compounds containing it tend to have weak dispersion interactions due to its anion's low polarizability. A commonly used ion-selective electrode utilizes a crystal containing it and lanthanum and is used to measure the concentration of the anionic form of this element. It is the only one of its group that does not exist in a positive oxidation state. Neil Bartlett created a compound containing this nonmetal and xenon; another compound containing it and uranium is used to separate uranium isotopes. First isolated by Henri Moissan in elemental form, FTP identify this halogen that is the most electronegative element.
