Applications

Chloroacetic acid is used in the production of pharmaceuticals, dyes, detergents, synthetic caffeine, glycine and thioglycolic acid, which acts as a stabilizer in PVC. It acts as a precursor to glyphosate and adrenaline. It also serves as a preservative and bacteriostat. Further, it is used as surface active agents and photosensitive chemicals. It is also used in the O-alkylation of salicylaldehyde and an active component in cosmetics. In addition, it is involved in the preparation of thickening agent carboxymethyl cellulose and carboxymethyl starch.

Notes

Incompatible with strong oxidizing agents, strong bases and strong reducing agents.

A convenient one-pot alternative to the Knoevenagel or Horner-Wadsworth-Emmons reactions for the synthesis of ɑ-unsubstituted cinnamic acids involves the reaction of chloroacetic acid with dimethyl phosphite in the presence of sodium methoxide, and treatment of the resulting phosphonoacetate salt with a benzaldehyde: J. Org. Chem., 46, 2514 (1981):
