Used in the synthesis of pharmaceutical intermediates, particularly in the development of active pharmaceutical ingredients (APIs) with antimicrobial and anti-inflammatory properties. It serves as a key building block in heterocyclic chemistry, facilitating the formation of fused ring systems like pyrimidines and quinazolines. Its amino and ester functional groups allow for selective derivatization, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies. Also applied in the preparation of dyes and functional materials due to its aromatic core and substitution pattern.
