Cyclohexanol is the organic compound with the formula (CH2)5CHOH. The molecule is related to cyclohexane ring by replacement of one hydrogen atom by a hydroxyl group.[2] This compound exists as a deliquescent colorless solid, which, when very pure, melts near room temperature. Billions of kilograms are produced annually, mainly as a precursor to nylon.[3]
