Benzalacetone-d5

Benzalacetone-d5 is a deuterated derivative of the organic compound benzalacetone. It is a yellowish crystalline solid that is soluble in organic solvents such as ethanol and acetone. Benzalacetone-d5 is primarily used as a chemical tracer in analytical chemistry, particularly in nuclear magnetic resonance (NMR) spectroscopy. Its deuterium atoms allow for more precise measurements of molecular structures and dynamics, as they have different resonance frequencies than hydrogen atoms. Chemically, benzalacetone-d5 is a ketone with the molecular formula C10H5D5O. It is synthesized through the reaction of benzaldehyde-d5 and acetone in the presence of a base catalyst. The deuterium atoms in benzalacetone-d5 are located in the alpha position of the carbonyl group and on the methyl groups adjacent to the carbonyl. Benzalacetone-d5 has a melting point of 67-69°C and a boiling point of 282°C. It is relatively stable and non-reactive under normal conditions, but can undergo typical ketone reactions such as nucleophilic addition and oxidation. Overall, benzalacetone-d5 is a useful tool for chemical analysis and research due to its unique isotopic properties and stability.
