Description and Uses
- 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.
