Synonyms:(R)-(-)-PROPYLENE GLYCEROL; (R)-(-)-PROPYLENE GLYCOL; (R)-(-)-PROPANEDIOL; (R)-(-)-1,2-Propyleneglycol; (R)-(-)-1,2-PROPANEDIOL; (R)-1,2-PROPANEDIOL; (R)-(-)-1,2-DIHYDROXYPROPANE;(R)-1,2-propandiol; (R-(–1,2-Propanediol))-IntermediateForTenofovir
(R) – (-) -1,2-Propanediol is a colorless to pale yellow transparent liquid. (R) The hydroxyl groups in the structure of 1,2-propanediol have certain nucleophilicity and are prone to undergo nucleophilic substitution reactions with alkyl halides and acyl halides to obtain corresponding ether and ester derivatives. Due to the two hydroxyl groups being in adjacent positions, they can undergo condensation reactions with aldehydes and ketones to form aldehydes or aldehyde compounds.
