Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of cardiovascular drugs. It plays a role in the preparation of compounds that modulate heart function and blood pressure due to its structural affinity with bioactive pyridazine derivatives. Its chloro and amine functional groups allow for further chemical modifications, making it valuable in medicinal chemistry for creating analogs with enhanced biological activity. Also utilized in research settings to explore new therapeutic agents targeting hypertension and related conditions.
