General description

Acetone-d6 (CD3COCD3, Hexadeuteroacetone) is the hexadeuterated form of acetone. It is 100% NMR (Nuclear Magnetic Resonance) solvent. It is widely employed in high resolution NMR studies due to its high chemical and isotopic purity. Absorption spectra of CD3COCD3 samples cooled in molecular jet (jet-cooled) have been evaluated in the range of 51000-54000cm-1. Collision of its molecular ions with a perdeuterated surface (C20D41 SAu) was investigated by ion-surface collision spectroscopy. The Infrared and Raman spectra of acetone-d6 have been analyzed.4 It undergoes H-2H exchange reaction with acetone d0 to afford acetone d1 and d5.
Acetone-d6 can be prepared by reacting heavy water with propyne-d4 in the presence of mercury catalyst.

Application

Acetone-d6 has been used as a solvent for the NMR (Nuclear Magnetic Resonance) spectral investigation of (S)-2-(6-((3-((15-carboxypentadecyl)disulfanyl)propoxy)carbonyloxy)benzo[d]thiazol-2-yl)-4,5-dihydrothiazole-4-carboxylic acid.
