Description

Formoterol Fumarate Dihydrate is a selective β2-adrenergic receptor agonist used as a long-acting bronchodilator. This high-purity active pharmaceutical ingredient (API) is critical for the development and manufacture of advanced respiratory medications. It is primarily required by pharmaceutical companies and research institutions focused on treating asthma and chronic obstructive pulmonary disease (COPD).

Application

• Active Pharmaceutical Ingredient (API) in long-acting bronchodilator formulations for asthma and COPD.
• Key component in dry powder inhalers (DPIs) and pressurized metered-dose inhalers (pMDIs).
• Used in pharmaceutical research and development for novel respiratory drug delivery systems.
• Reference standard in analytical laboratories for quality control and method validation.
• Starting material for the synthesis of related pharmaceutical compounds in advanced research.
