The compound is also formed as a by-product of the thermal decomposition of tris (2-chloroisopropyl) phosphate .

properties

2-chloro-1-propanol is a colorless liquid with a faint odor that is completely miscible with water. 2-chloro-1-propanol is chiral , i.e. it contains a stereocenter . There are thus two stereoisomers, the ( R ) enantiomer and the ( S ) enantiomer. The 1: 1 mixture ( racemate ) of ( R ) - and ( S ) -enantiomer is called ( RS ) -2-chloro-1-propanol or (±) -2-chloro-1-propanol. When “2-chloro-1-propanol” is mentioned in the scientific literature or in this article without further details, the racemate is meant.
