Except for extremely rare cases, organohalides are not produced biologically, but many pharmaceuticals are organohalides. A few halocarbons are produced in massive amounts by microorganisms. The first synthesis of halocarbons was achieved in the early 1800s.

Production began accelerating when their useful properties as solvents and anesthetics were discovered. Development of plastics and synthetic elastomers has led to greatly expanded scale of production. A substantial percentage of drugs are halocarbons. There are several thousand complex halocarbons known, produced mainly by marine species. Although chlorine compounds are the majority of the discovered compounds, bromides, iodides and fluorides have also been found. These three representatives, thyroxine from humans, tyrian purple from snails and fluoroacetate from plants, also show that unrelated species use halocarbons for several purposes. Many organic iodides are known, but few are of major industrial importance.
Iodide compounds are mainly produced as nutritional supplements. Prior to 1940, iodides were the predominant antithyroid agents. This treatment is seldom used today as a stand-alone therapy despite the rapid improvement of patients immediately following administration. In addition, the functionality of iodides fades after the initial treatment period. An “escape from block” is also a concern, as extra stored TH may spike following discontinuation of treatment.
