2-Octanol (octan-2-ol, 2-OH) is a fatty alcohol. It is a secondary eight-carbon chiral compound. 2-Octanol is a colorless liquid that is poorly soluble in water but soluble in most organic solvents.

It is used such as or as a raw material in various applications: flavors and fragrances, paints and coatings, inks, adhesives, home care, lubricants and fuels. 2-Octanol can be a biobased alternative of 2-ethylhexanol and its derivates in numerous applications.

Manufacturing[edit]

2-Octanol is produced from castor oil through a cracking process. It is created as a by-product of sebacic acid manufacturing.[8] Nowadays, India and China are the key producing countries of castor oil. Consequently, the majority of 2-Octanol production comes from these two countries: China & India.

Uses[edit]

2-Octanol is mainly used as:

It can also be used as a chemical intermediate for production of various other chemicals:
