Quantity	Value	Units	Method	Reference	Comment
Δ_fH°_gas	88.86 ± 0.91	kcal/mol	Review	Roux, Temprado, et al., 2008	There are sufficient literature values to make a qualified recommendation where the suggested value is in good agreement with values predicted using thermochemical cycles or from reliable estimates. In general, the evaluated uncertainty limits are on the order of (2 to 4) kJ/mol.
