Ethanol-d(CAS: 925-93-9)

Ethanol-d, also known as deuterated ethanol, has a CAS number of 925-93-9. It is a colorless, flammable liquid with a slightly sweet odor. Ethanol-d is miscible with water and various organic solvents. It is less reactive than regular ethanol due to the deuterium substitution. Ethanol-d has a higher boiling point (78.5°C) compared to ethanol (78.37°C) and a higher molecular weight (46.07 u). It is commonly used in NMR spectroscopy for deuterium exchange reactions.

Ethanol-d is typically synthesized by reacting ethanol with deuterium gas (D2) over a catalyst such as Pd/C. The reaction selectively deuterates the hydroxyl group, resulting in deuterium substitution. This method provides a high yield of Ethanol-d with good purity. The process is carried out under mild conditions, and the catalyst is removed by filtration before purification.

Ethanol-d, (CAS: 925-93-9), is widely used in the pharmaceutical industry for deuterium exchange reactions in metabolic studies and drug development. It is also utilized in polymer research for studying polymer solubility and degradation. Additionally, it is employed in the semiconductor industry for etching processes and in sensor technology for calibration purposes.

When handling Ethanol-d (CAS: 925-93-9), it is important to wear appropriate personal protective equipment (PPE) such as gloves and goggles. Store in a cool, well-ventilated area away from sources of ignition. Use a fume hood during handling to minimize exposure. In case of spill, absorb with sand or other inert material and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed information and emergency procedures.
