Pinacolyl alcohol (also known as 3,3-dimethylbutan-2-ol and as pine alcohol) is one of the isomeric hexanols and a secondary alcohol. Pinacolyl alcohol appears on the List of Schedule 2 substances of the Chemical Weapons Convention as a precursor for the nerve agent soman .
The total area of the 1 ppm CH 2 peak will be twice that of the 2.5 ppm CH peak. The CH 2 peak will be split into a doublet by the CH peak—with one peak at 1 ppm + 3.5 Hz and one at 1 ppm − 3.5 Hz (total splitting or coupling constant is 7 Hz). In consequence the CH peak at 2.5 ppm will be split twice by each proton from the CH 2. The first ...
The data are then processed through Fourier transformation along both the t 1 and t 2 axes, creating a 2D spectrum with peaks plotted along the diagonal and off-diagonal. When interpreting the COSY spectrum, diagonal peaks correspond to the 1D chemical shifts of individual nuclei, similar to the standard peaks in a 1D NMR spectrum.
Available through Wiley Online Library [3] (John Wiley & Sons), SpecInfo on the Internet NMR is a collection of approximately 440,000 NMR spectra (organized as 13 C, 1 H, 19 F, 31 P, and 29 Si NMR databases). The data are accessed via the Internet using a Java interface and are stored in a server developed jointly with BASF. The software ...
Pinacolone (3,3-dimethyl-2-butanone) is an important ketone in organic chemistry. It is a colorless liquid with a slight peppermint or camphor odor. It is a precursor to triazolylpinacolone in the synthesis of the fungicide triadimefon and in synthesis of the herbicide metribuzin. The molecule is an unsymmetrical ketone. The α-methyl group can ...
3-Methyl-2-butanol (IUPAC name, commonly called sec-isoamyl alcohol) is an organic chemical compound. It is used as a solvent and an intermediate in the manufacture of other chemicals. [ 3 ]
