Isobutyl carbinol can be synthesized from isobutanol by conversion into isovaleraldehyde, which is subsequently reduced to isobutyl carbinol by means of sodium amalgam . It is a colourless liquid of density g/cm³ (0 °C), boiling at °C, slightly soluble in water, and easily dissolved in organic solvents. It has a characteristic strong smell and a sharp burning taste. Amyl alcohol has an oral LD50 of 200 mg/kg in mice,  suggesting that it is significantly more toxic than ethanol. On passing the vapour through a red-hot tube, it decomposes into acetylene , ethylene , propylene , and other compounds. It is oxidized by chromic acid to isovaleraldehyde , and it forms addition compounds crystals with calcium chloride and tin(IV) chloride . 
As shown in Figure 5, the information preceding each equal sign (=) will be displayed as a Field title in the Text display of the spectrum and can optional be displayed with the Plot of the spectrum. The information following the equals sign (=) will appear following the Field header. Entry of Field contents (string) must conform to the rules above. In order for this display to occur, the Field titles must be registered in the Display comment field options dialog box shown in Figure 4 ( View/Comment fields options ). When the Tags have been entered into the Comment Field Options dialog box, they will not be displayed in the Comments field of the Text Information window. Figure 5 shows a spectrum (Plot and Text) with added Field headers.
