Description and Uses

1-Octanol (111-87-5) is a colorless and transparent liquid with the chemical formula C8H18O. It is a fatty alcohol consisting of a linear, saturated chain of eight carbon atoms. Although 1-Octanol is not highly soluble in water, it can dissolve easily in alcohol, ether, and chloroform. This compound is commonly used as a raw material in the production of fragrances, octanal, octanoic acid, and its esters. It also functions as a solvent, defoamer, and lubricating oil additive. Notably, 1-Octanol poses a low level of toxicity, but it can be irritating to the skin and eyes. Nonetheless, it is considered safe to use under normal conditions because of its low vapor pressure.

1-Octanol is used as a precursor to prepare esters, which is used in perfumes and flavorings. It is used as food additive, anti-foaming agent and emulsifier in anti-rust emulsions. It is widely involved in chemical industry for the synthesis of ethoxylates, alkyl sulfates and ether sulfates. It is used as a solvent in paints, varnishes, waxes, and surface coatings and mainly involved in agricultural chemistry to inhibit excessive growth of tobacco plants.
