For transportation it may be stenched. It is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. It is easily ignited. Its vapors are heavier than air. Any leak can be either liquid or vapor. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used as a fuel, an aerosol propellant, in cigarette lighters, and to make other chemicals.","PubChemId":7843,"RefCount":2,"RefCur":"","References":[{"Name":"Wikipedia","Urls":[{"Link":"https://en.wikipedia.org/wiki/Butane","Name":"Butane","Sub":false}]},{"Name":"PubChem","Urls":[{"Link":"https://pubchem.ncbi.nlm.nih.gov/compound/7843","Name":"Butane","Sub":false}]},{"Name":"ChEMBL","Urls":[{"Link":"https://www.ebi.ac.uk/chembl/explore/compound/CHEMBL134702","Name":"Butane","Sub":false}]},{"Name":"ChEBI","Urls":[{"Link":"https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:37808","Name":"Butane","Sub":false}]},{"Name":"Common Chemistry","Urls":[{"Link":"https://commonchemistry.cas.org/detail?cas_rn=106-97-8","Name":"Butane","Sub":false}]},{"Name":"KEGG","Urls":[{"Link":"https://www.kegg.jp/entry/C21390","Name":"Butane","Sub":false}]},{"Name":"UNII","Urls":[{"Link":"https://gsrs.ncats.nih.gov/ginas/app/ui/substances/6LV4FOR43R","Name":"Butane","Sub":false}]},{"Name":"EPA DSSTox","Urls":[{"Link":"https://comptox.epa.gov/dashboard/chemical/details/DTXSID7024665","Name":"Butane","Sub":false}]}],"Refs":["National Center for Biotechnology Information.
