Isobornyl cyclohexanol (IBCH) is an organic compound used primarily as a fragrance because of its aroma which is similar to sandalwood oil. Its chemical structure is closely related to that of both α-Santalol and β-Santalol,[3] which are the primary constituents of sandalwood oil.

Sandalwood trees are endangered due to overharvesting,[4] leading to a high cost for the natural oil. IBCH is therefore produced as an economical alternative to the natural product.
