Ammonium-D4 bromide

Ammonium-D4 bromide is a chemical compound that is commonly used in biochemical research and analysis. It is a deuterated form of ammonium bromide, which means that it contains four deuterium atoms instead of the four hydrogen atoms in normal ammonium bromide. This makes it useful in NMR spectroscopy, as it can be used as a reference standard for determining the chemical shifts of other molecules. Ammonium-D4 bromide is a white crystalline powder that is soluble in water. It has a molecular weight of 98.95 g/mol and a melting point of 452°C. It is commonly used in the preparation of other deuterated compounds, such as deuterated solvents for NMR spectroscopy. The chemical formula for Ammonium-D4 bromide is NH4BrD4, which indicates that it is composed of one ammonium ion (NH4+) and one bromide ion (Br-) that have been fully deuterated. The ammonium ion is a positively charged polyatomic ion that contains one nitrogen atom and four hydrogen atoms. The bromide ion is a negatively charged monatomic ion that contains one bromine atom. Overall, Ammonium-D4 bromide is a useful compound in biochemical research and analysis due to its deuterated nature and its ability to be used as a reference standard in NMR spectroscopy.
