Like other diols, this viscous colourless liquid is used as plasticizer and also forms polyesters that are used as emulsifying agents and resin intermediates.. 1,5-Pentanediol is produced by hydrogenation of glutaric acid and its derivatives. The branched isomers are more stable (have lower heat of formation and heat of combustion) than n-pentane. However, the melting point of neopentane, the most heavily branched of the three, is 100 °C higher than that of isopentane. Pentanes are solvents in many ordinary products, e.g. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. The same tends to be true for the melting points of alkane isomers, and that of isopentane is 30 °C lower than that of n-pentane. This chemical has some pollutant properties, but it is widely used in industrial and scientific settings.
