It is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. It is easily ignited. The vapors are heavier than air. Any leak can either be liquid or vapor. It can asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.","PubChemId":6360,"RefCount":2,"RefCur":"","References":[{"Name":"Wikipedia","Urls":[{"Link":"https://en.wikipedia.org/wiki/Isobutane","Name":"Isobutane","Sub":false}]},{"Name":"PubChem","Urls":[{"Link":"https://pubchem.ncbi.nlm.nih.gov/compound/6360","Name":"Isobutane","Sub":false}]},{"Name":"ChEMBL","Urls":[{"Link":"https://www.ebi.ac.uk/chembl/explore/compound/CHEMBL2106398","Name":"Isobutane","Sub":false}]},{"Name":"ChEBI","Urls":[{"Link":"https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:30363","Name":"Isobutane","Sub":false}]},{"Name":"Common Chemistry","Urls":[{"Link":"https://commonchemistry.cas.org/detail?cas_rn=75-28-5","Name":"Isobutane","Sub":false}]},{"Name":"HMDB","Urls":[{"Link":"https://hmdb.ca/metabolites/HMDB0253605","Name":"Isobutane","Sub":false}]},{"Name":"KEGG","Urls":[{"Link":"https://www.kegg.jp/entry/D04623","Name":"Isobutane","Sub":false}]},{"Name":"UNII","Urls":[{"Link":"https://gsrs.ncats.nih.gov/ginas/app/ui/substances/BXR49TP611","Name":"Isobutane","Sub":false}]},{"Name":"EPA DSSTox","Urls":[{"Link":"https://comptox.epa.gov/dashboard/chemical/details/DTXSID1026401","Name":"Isobutane","Sub":false}]}],"Refs":["National Center for Biotechnology Information.
