[Description]

1,2-Pentanediol, also known as 1,2-dihydroxypentane, is a colorless and odorless liquid which is miscible with water and polar organic solvents. It is a chiral molecule with one stereocenter. The compound is usually made by treating a mixture of 1-pentene and formic acid with hydrogen peroxide at<100 ℃. An optically active R-enantiomer of 1,2-pentanediol can be prepared by fermentation.
