FPLC columns are stored in a 20% solution of this substance,
FPLC columns are stored in a 20% solution of this substance, whose hydrogen NMR spectrumshows a quadruplet around 3.7 ppm, a triplet around 1.2 ppm, and a broad singlet around 2.6 ppm.It can be purified to 96% by volume before dessication must be used, because this substance formsan azeotrope with water at that concentration. It is oxidized to acetaldehyde in biological systems.One method of obtaining this compound involves using enzymes capable of breaking down (*)cellulose; that method is used to extract this substance from corn. This substance is more commonlyproduced from yeast using fermentation. For 10 points, name this substance with formula C2H5OH, atwo-carbon alcohol found in drinks.
