ETHANOL-D is used in alcoholic beverages in suitable dilutions. Other uses are as solvent in laboratory and industry , in the manufacture of denatured alcohol, pharmaceuticals, in perfumery , in organic synthesis.

?? ??

ETHANOL-D is a deuterated NMR solvent,it can be prepared by reacting tetraethylorthosilicate with deuterium oxide.

?? ??

Ethan(ol-d) (ethanol-d, ethanol-d1) is a deuterated NMR solvent useful in NMR-based research and analyses. It can be prepared by reacting tetraethylorthosilicate with deuterium oxide. The hydrogen bonding in ethanol-d1 has been investigated based on Raman spectral data. The far infrared (FIR) spectrum of ethanol-d1 has been studied using ab initio calculations.
