Description

Umeclidinium Bromide CAS NO 869113-09-7 is a long-acting muscarinic antagonist (LAMA) pharmaceutical compound. It is a critical active pharmaceutical ingredient (API) used in the treatment of chronic obstructive pulmonary disease (COPD). This high-purity compound is essential for pharmaceutical manufacturers and research institutions developing and producing advanced respiratory therapies to improve patient outcomes.

Application

• Primary Active Pharmaceutical Ingredient (API) in combination inhalers for the maintenance treatment of Chronic Obstructive Pulmonary Disease (COPD).
• Key component in the formulation of dry powder inhalers (DPIs) and pressurized metered-dose inhalers (pMDIs).
• Used in pharmaceutical R&D for developing new long-acting bronchodilator therapies.
• Reference standard in analytical laboratories for quality control and method validation.
• Intermediate in the synthesis of novel muscarinic receptor antagonists for respiratory research.
• Used in preclinical and clinical studies investigating new delivery mechanisms for pulmonary drugs.
