1. Pesticide field: trichloroacetyl chloride is an important raw material for the synthesis of chlorpyrifos, methyl chlorpyrifos and other new generation alternative pesticide products. Chlorpyrifos and methyl chlorpyrifos have the characteristics of broad spectrum, high efficiency, low toxicity and low residue, and have been widely used in the world. In addition, trichloroacetyl chloride is also an important raw material for the synthesis of high efficiency and low toxicity herbicides.

2. Pharmaceutical field: trichloroacetyl chloride also has certain applications in the pharmaceutical field, mainly used in the synthesis of fungicides and polycyclic antimicrobials and other drugs.

3. Organic intermediates and fine chemical fields: trichloroacetyl chloride can be used as an important raw material for organic synthesis, for the production of high-grade auxiliaries such as polycyclic aromatic ethers, which are widely used in the two major fields of polyamide (nylon) and polyester. In addition, trichloroacetyl chloride can also be used to synthesize other organic intermediates and fine chemical products.
