Application:
4-Amino-3,5-Dichloropyridine (CAS: 22889-78-7) is the interemdiate of Roflumilast (CAS: 162401-32-3). Roflumilast is a selective oral phosphodiesterase-4 (PDE-4) inhibitor and a benzamide compound. It was developed by the German company Altana in 1993 and is the only oral PDE-4 inhibitor used to treat respiratory tract diseases approved for sale. Roflumilast is the first drug of its kind to target severe chronic obstructive pulmonary disease (COPD), and it is also the first oral anti-inflammation drug specifically developed for COPD patients.
