Benzene-d6(CAS: 1076-43-3)

Benzene-d6 is a colorless liquid with a molecular weight of 114.17 g/mol. It has a low solubility in water but is highly soluble in organic solvents. This compound is less reactive than benzene due to the deuterium substitution. Benzene-d6 exhibits a high boiling point and is flammable. It is often used in NMR spectroscopy as an internal standard.

Benzene-d6 is synthesized by deuterium labeling of benzene. The reaction involves the replacement of hydrogen atoms in benzene with deuterium atoms using a deuterium source and a suitable catalyst, such as palladium or rhodium. The yield is typically around 90-95%, with good selectivity towards deuterium substitution.

Benzene-d6 is primarily used in the field of analytical chemistry, particularly in nuclear magnetic resonance (NMR) spectroscopy. It serves as an internal standard in NMR analysis, aiding in the accurate measurement of chemical shifts. Additionally, it has applications in the pharmaceutical industry for quality control and in the semiconductor industry for precise chemical analysis.

Benzene-d6 should be handled with caution due to its flammability and potential health effects. Lab personnel should wear appropriate personal protective equipment (PPE), including safety glasses and gloves. It should be stored in a cool, well-ventilated area, away from sources of ignition. In case of spill, it should be cleaned up immediately using appropriate methods, and the area should be fumigated. A Safety Data Sheet (SDS) should always be consulted for detailed handling procedures.
