Used primarily as an intermediate in the synthesis of carbamate pesticides, particularly in the production of insecticides like carbaryl. It plays a key role in forming the carbamate ester linkage, which is essential for the biological activity of these compounds. Due to its reactivity, it is also employed in organic synthesis for introducing the N-methylcarbaniloyl group. Its application is mostly confined to controlled industrial processes owing to its toxicity and instability.
