Description

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.

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.

Other Notes

Contains 2,2-dichloropropionic acid
