Special gases provide important source materials for chemical synthesis. These gases are of interest as building blocks due to their structural variety. Fluorinated gases are broadly used. They can, on the one hand, be used as fluorination reagents e.g. for the introduction of individual fluorine atoms in a molecule. Inorganic fluorinated gases are used preferably. On the other hand, they also introduce whole structural elements into complex organic molecules.
Their pharmacokinetic properties are improved with the introduction of fluorine substitutes in active agents. By means of “late-stage-fluorination”, the fluorine-containing groups are introduced into molecules in one of the last synthesis steps.
Moreover, multiple gases are used as monomers in polymerisation reactions. These reagents comprise both non-substituted alkenes and alkines as well as halogenated gases and cyclic compounds.
In addition to these usage areas, gases are also indispensable for many analytical methods. For example, they can be used as standards in environmental analytics.
