| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| biological activity | 2-Chloroacetamide is a preservative and a herbicide for dry and paddy fields. 2-Chloroacetamide is a fungicide in agriculture, glue, paints and coatings. 2-Chloroacetamide inhibits very long-chain fatty acid elongation enzymes. |
| uses | chloroacetamide is used in organic synthesis, pharmaceutical intermediates and synthesis of chloroacetonitrile, sulfanilamide -3-methoxy pyrazine, sulfamethoxazole pyrazine and other organic compounds. |
| production method | results from the reaction of ethyl chloroacetate with ammonia. First, cool ethyl chloroacetate to below 10 ℃, slowly add ammonia water (relative density 0.9) under stirring, immediately precipitate white crystals, continue stirring for 1H after adding ammonia water, and filter out crystals, then wash off ammonium chloride with ammonia, filter dry as far as possible is the crude product, and then recrystallized with ethanol to obtain the finished product. |
