Chloroacetyl Chloride (CAS 79-04-9) is a highly reactive bifunctional organic reagent that appears as a clear colorless to slightly yellow liquid, introduces chloroacetyl groups into chemical structures, and serves as a building block for acetanilide herbicides, local anesthetics and antibiotics. It is valued for its ability to introduce chloroacetyl groups into chemical structures with high precision.
It is indispensable in the agricultural sector for manufacturing acetanilide herbicides. Its technical grade purity ensures efficient conversion rates and high yields in the production of active crop protection ingredients.
In the pharmaceutical industry, it serves as a critical intermediate for local anesthetics and antibiotics. This liquid is a powerful lachrymator, requiring specialized handling equipment and rigorous safety protocols in manufacturing sites.
