General description
1,2-Propanediol can be obtained as a byproduct in the dehydration of glycerol to hydroxyacetone.It can undergo condensation with sebacic acid and citric acid in the absence of catalyst to give poly((1,2-propanediol-sebacate)-citrate) (PPSC), an elastomeric polyester, which can find applications in tissue engineering and drug delivery.
Application
1,2-Propanediol has been used:
- for removing excess Oil Red O stain in zebrafish larvae
- in the preparation of alginate hydrogels
- for the dissolution of androstenone
- for the calibration of cone beam scanner in computed tomography
