Isocetane (2,2,4,4,6,8,8-heptamethylnonane) is a highly branched alkane used as a reference in determining the cetane number of diesel. [ [http://www.findarticles.com/p/articles/mi_m0FZX/is_3_68/ai_84903243 New system offers faster, easier method for cetane measurement] by Bill Siuru, "Diesel Progress, North American Edition", March, 2002] It is given a cetane number of 15. Isocetane replaced 1-methylnaphthalene as the lower reference for cetane number (1-methylnaphthalene has cetane number zero) owing to the expense of 1-methylnaphthalene, and difficulty in safe handling.
