1,2-Propadiene-1,1,3,3-d4, also known as deuterated propylene or d4-propylene, is a deuterated form of propadiene, a simple hydrocarbon with the formula C3H4. This compound features a three-carbon chain with two double bonds, specifically between the first and second, and the second and third carbon atoms. The deuteration indicates that four hydrogen atoms in the molecule are replaced by deuterium, a stable isotope of hydrogen, which is represented by the "d" in its name. This substitution alters the physical and chemical properties of the compound, such as its mass and vibrational characteristics, making it useful in various applications, including NMR spectroscopy and studies involving isotopic labeling. 1,2-Propadiene-1,1,3,3-d4 is typically a colorless gas or liquid at room temperature and is flammable. Its reactivity is similar to that of non-deuterated propadiene, participating in typical alkene reactions such as polymerization and addition reactions.
