Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its structure allows for the development of compounds with selective activity against broadleaf weeds in cereal crops. It is also employed in the preparation of more complex picolinic acid derivatives that exhibit biological activity in crop protection. Due to the presence of both amino and ester functional groups, it serves as a versatile building block in heterocyclic chemistry for creating active ingredients in modern pesticide formulations.
