What is (S)-(-)-2-Chloropropionic acid?
Chemical properties
Colourless Oil
The Uses of (S)-(-)-2-Chloropropionic acid
Through the stereo displacement of (S)-(-)-2-Chloropropionic acid PPAR Agonist can be synthesized via asymmetric hydrogenation of a cinnamic acid derivative.
Definition
ChEBI: A monocarboxylic acid that is propanoic acid substitued at position 2 by a chloro group (the S-enantiomer).
Flammability and Explosibility
Non flammable
Purification Methods
Purify the acid by fractionating twice through a 115cm Podbielniak column (p 11, calculated 50 theoretical plates at atmospheric pressure) using a take-off ratio of 1:5. The acid chloride is prepared by dissolving the acid in SOCl2, adding a few drops of PCl3, refluxing and then distilling through a 30cm column, b 53o/100mm, [] -4.6o (neat), d 1.2689, n1.4368.
