Deuterated hydrocarbons are organic compounds where hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen. This substitution alters the physical and chemical properties of the hydrocarbons, making them useful in various scientific applications, including nuclear magnetic resonance (NMR) spectroscopy and studies of reaction mechanisms. These compounds are often used in research to trace molecular pathways and understand complex chemical reactions. Deuterated hydrocarbons can also improve the sensitivity of analytical techniques, allowing scientists to gather more precise data. Their unique properties make them valuable tools in fields such as chemistry, biology, and materials science.
