Umeclidinium Bromide [CAS: 869113-09-7] is a long-term maintenance bronchodilator for airflow obstruction in adults diagnosed with chronic obstructive pulmonary disease (COPD).

Umeclidinium Bromide: Use and Commercial Availability    

Umeclidinium bromide belongs to the class of long-acting muscarinic acetylcholine antagonists. It prevents the tightening of large airway muscles. This medication is for the maintenance treatment of individuals diagnosed with chronic obstructive pulmonary disease (COPD). Umeclidinium Bromide is available under the brand name Incruse Ellipta, which contains the active ingredient, Umeclidinium Bromide.

Umeclidinium Bromide Structure and Mechanism of Action 

The chemical name of Umeclidinium Bromide is 4-(Hydroxydiphenylmethyl)-1-[2-[(phenylmethyl)oxy]ethyl]-1-azabicyclo[2.2.2]octanium bromide. Its chemical formula is C29H34BrNO2, and its molecular weight is approximately 508.5 g/mol.

Umeclidinium blocks muscarinic receptor M3 at the smooth muscle resulting in bronchodilation.

Umeclidinium Bromide Impurities and Synthesis 

Umeclidinium Bromide impurities can arise during synthesis1 due to storage or using specific raw materials and intermediates in preparation. These impurities encompass related compounds, degradation products, and process impurities. Stringent quality control measures and analytical methods are crucial to ensure the purity and safety of Umeclidinium Bromide for patient use.

Daicel provides a comprehensive Certificate of Analysis (CoA) for Umeclidinium Bromide impurity standards such as (1-Azabicyclo[2.2.2]octan-4-yl)(diphenyl)methanol and 4-(hydroxydiphenylmethyl)-1-(2-hydroxyethyl)quinuclidin-1-ium bromide. The CoA includes detailed characterization data such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Additionally, upon delivery, we give 13C-DEPT. Daicel possesses the technology and expertise to synthesize any unknown Umeclidinium Bromide impurity or degradation product.
