1,5-Pentanediol is the
organic compound
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-co ...

HO(CH)OH. Like other
diols, this viscous, colorless liquid is used as a
plasticizer and also forms
polyesters, which are used as emulsifying agents and resin intermediates.
Synthesis and reactions
1,5-Pentanediol is produced by
hydrogenation
Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to redox, reduce or Saturated ...
of
glutaric acid and its derivatives. It can also be prepared by
hydrogenolysis of
tetrahydrofurfuryl alcohol.
1,4-Pentadiene can be prepared from 1,5-pentadiol via the diacetate.
Contamination of Bindeez
A toy called ''
Bindeez'' (''Aqua Dots'' in North America) was recalled by the distributor in November 2007 due to the unauthorized substitution of 1,5-pentanediol with
1,4-butanediol. The toy consists of small beads that stick to each other when sprinkled with water. 1,4-Butanediol, which when ingested is metabolized to
gamma-hydroxybutyric acid, was detected by
GC-MS. ChemNet China lists the price of 1,4-butanediol at between US$1,350–2,800/tonne, while the price for 1,5-pentanediol is about US$9,700/tonne.
