| Application: | • 2-Chloropropionic acid is used in the preparation of propargyl 2-chloropropionate (PCP), an atom transfer radical polymerization (ATRP) initiator, by the esterification of propargyl alcohol. • It can be employed in the synthesis of a biologically active chitin derivative, (1-carboxyethyl) chitosan. • It can be treated with o-phenylenediamine phosphate to synthesize benzimidazole derivatives. |
| Biochem/physiol Actions: | 2-Chloropropionic acid on oral administration induces necrosis of granule cell layer of rat cerebellum. |
| General description: | (S)-2-Chloropropionic acid is the building block for the synthesis of aryloxyphenoxypropionic acid herbicides. 2-Chloropropionic acid is the raw material for production of pesticides, dyestuffs and agro- and forest chemicals. |
