Weringa, W. D. published the artcile< Mass spectra of spiroalkanones with five-and six-membered rings>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is mass spectra spiroalkanone.
The mass spectral fragmentations of 3 spiroundecanones and 4 dispirohexadecanones with 6-membered rings, and of 2 spirononanones with 5-membered rings are recorded and discussed. The fragmentation patterns for the spiro[4.4]nonanones and the spiro[5.5]undecanones were determined by using specific D labeling and in some cases the measurement of metastable transitions by the defocusing technique. The most important fragment ions in the spectra of 4 dispirohexadecanones could be explained by assuming the same types of fragmentation as found for the monospiro ketones. The composition of the fragment ions was checked by high resolution mass measurements.
Organic Mass Spectrometry published new progress about Mass spectra. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate.
