General description

Chloroacetyl chloride is used as a chlorinating agent, acylating agent, precursor to monochloroketene, and as a building block for cyclization.

Chloroacetyl chloride causes the acylation of cyano-pyrazoline during the synthesis of secondary amine-substituted cyano-pyrazoline derivatives.

Application

Chloroacetyl chloride can be used for chloroacetylation and chemical modification of poly(glycidyl methacrylate). Chloroacetyl chloride was used to study the in vitro metabolism of chloroacetamide herbicides by rat and human liver microsomes. Chloroacetyl chloride was used in the synthesis of some novel quinoline derivatives having antileishmanial activity.

Acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methyl-phenyl)-acetamide], alachlor [N-(methoxymethyl)-2-chloro-N-(2, 6-diethyl-phenyl)acetamide], butachlor [N-(butoxymethyl)-2-chloro-N-(2,6-diethyl-phenyl)acetamide], and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide] are pre-emergent herbicides used in the production of agricultural crops. These herbicides are carcinogenic in rats: acetochlor and alachlor cause tumors in the nasal turbinates, butachlor causes stomach tumors

Polymers with antibacterial activity have been synthesized by chemical modification of poly(glycidyl methacrylate). The glycidyl methacrylate was polymerized by the free radical polymerization technique. The poly(glycidyl methacrylate) was hydrolyzed and was chloroacetylated using chloroacetyl chloride. The chloroacetylated product was modified

Some novel quinoline derivatives were prepared and tested for antileishmanial activity. 2-(2-Methylquinolin-4-ylamino)-N-phenylacetamide (2) was found to be significantly more active than the standard antileishmanial drug sodium antimony gluconate (SAG) in reducing the parasite load both in the spleen and liver
