Propane containing too much propene is not suited for most vehicle fuels. HD-5 is a specification that establishes a maximum concentration of 5% propene in propane. Propane and other LP gas specifications are established in ASTM D-1835. [46] All propane fuels include an odorant, almost always ethanethiol, so that the gas can be smelled easily ...
Propane/butane blends are also listed in these specifications. Propylene, butylenes and various other hydrocarbons are usually also present in small concentrations such as C 2 H 6, CH 4, and C 3 H 8. HD-5 limits the amount of propylene that can be placed in LPG to 5% and is utilized as an autogas specification. [12]
Propane does not have health effects other than the danger of frostbite or asphyxiation. The National Propane Gas Association has a generic MSDS available online here. (Issued 1996) MSDS from Suburban Propane, L.P dated 5/2013 in the SDSdata.org database

Since the longest continuous chain in isobutane contains only three carbon atoms, the preferred IUPAC name is 2-methylpropane but the locant (2-) is typically omitted in general nomenclature as redundant; C2 is the only position on a propane chain where a methyl substituent can be located without altering the main chain and forming the ...
