Ethyl 5-amino-6-iodopyridine-2-carboxylate is primarily used as a key intermediate in the synthesis of various pharmaceutical compounds. Its structure allows for further functionalization, making it valuable in the development of drugs targeting specific biological pathways. It is particularly useful in the preparation of heterocyclic compounds, which are often explored for their potential therapeutic effects, including antimicrobial, anticancer, and anti-inflammatory properties. Additionally, it serves as a building block in organic synthesis for creating complex molecules in medicinal chemistry research. Its iodine substituent also makes it a useful precursor for cross-coupling reactions, enabling the construction of more elaborate chemical structures.
