Infobox references

1-Methylnaphthalene is an aromatic hydrocarbon. It has a cetane number of zero, and was previously used as the lower reference for cetane number. However, due to the expense and handling difficulty of 1-Methylnaphthalene, it was replaced in this capacity by isocetane, with a CN of 15[2].
