Automobile airbags and aircraft evacuation slides Older airbag formulations contained mixtures of oxidizers and<unk>  and other agents including ignitors and accelerants. An electronic controller detonates this mixture during an automobile crash: : The same reaction occurs upon heating the salt to approximately 300 °C. The<unk>  that is formed is a potential hazard alone and, in automobile airbags, it is converted by reaction with other ingredients, such as potassium nitrate and silica. In the latter case, innocuous<unk>  silicates are generated. While<unk>  is still used in evacuation slides on modern aircraft, newer-generation automotive air bags contain less sensitive explosives such as nitroguanidine or guanidine nitrate. Organic and inorganic synthesis Due to its explosion hazard,<unk>  is of only limited value in industrial-scale organic chemistry. In the laboratory, it is used in organic synthesis to introduce the<unk>  functional group by displacement of halides. The<unk>  functional group can thereafter be converted to an amine by reduction with either in ethanol or lithium aluminium hydride or a tertiary phosphine, such as triphenylphosphine in the Staudinger reaction, with Raney nickel or with hydrogen sulfide in pyridine.<unk>  is a versatile precursor to other inorganic<unk>  compounds, e.g., lead<unk>  and silver<unk> , which are used in detonators as primary explosives. These<unk> s are significantly more sensitive to premature detonation than<unk>  and thus have limited applications. Lead and silver<unk>  can be made via double displacement reaction with<unk>  and their respective nitrate (most commonly) or acetate salts.<unk>  can also react with the chloride salts of certain alkaline earth metals in aqueous solution, such as barium chloride or strontium chloride to respectively produce barium<unk>  and strontium<unk> , which are also relatively sensitive primarily explosive materials. These<unk> s can be recovered from solution through careful desiccation. Biochemistry and biomedical uses<unk>  is a useful probe reagent and a preservative. In hospitals and laboratories, it is a biocide; it is especially important in bulk reagents and stock solutions which may otherwise support bacterial growth where the<unk>  acts as a bacteriostatic by inhibiting cytochrome oxidase in gram-negative bacteria; however, some gram-positive bacteria (streptococci, pneumococci, lactobacilli) are intrinsically resistant. Agricultural uses It is used in agriculture for pest control of soil-borne pathogens such as Meloidogyne incognita or Helicotylenchus dihystera. It is also used as a mutagen for crop selection of plants such as rice, barley or oats.
