1,9-Nonanediol

1,9-Nonanediol, also known as nonamethylene glycol, is a diol with the molecular formula HO(CH$2$)$9$OH. It is a colorless solid, which is sparingly soluble in water but readily soluble in ethanol.

1,9-nonanediol can be produced by isomerization of allyl alcohol. It can also be obtained by reacting methyl oleate with triethylsilyl hydrotrioxide and lithium aluminum hydride.

1,9-Nonanediol is used as a monomer in the synthesis of some polymers. It is also used as an intermediate in the manufacturing of aromatic chemicals and in the pharmaceutical industry.
