Umeclidinium-d10 bromide（Cat No.:S000283） is a deuterated form of umeclidinium bromide, where ten hydrogen atoms are replaced with deuterium, significantly enhancing its molecular stability. This makes it highly useful as an internal standard for precision in analytical methods like mass spectrometry and NMR spectroscopy. Umeclidinium bromide is a long-acting muscarinic antagonist (LAMA) used primarily in the treatment of chronic obstructive pulmonary disease (COPD) to relax the muscles in the airways and improve breathing.
