Rapid determination of olefin position in organic compounds in microgram range by ozonolysis and gas chromatography. Alkylidene analysis

Mammalian pheromone studies, IV*. Terpenoid Compounds and Hydroxy Esters from the Dorsal Gland of the Springbok, Antidorcas marsupialis

“…The resulting hydroxy ester also served as model compound in the identification of the other hydroxy esters. The position of the double bond in component (3651) was determined by micro-ozonolysis [10] and Z configuration was assigned to this double bond by comparison of the olefinic resonance in the X H NMR spectrum of the isolated material with olefinic patterns simulated with E and Z coupling constants [11].…”

Rapid Identification and Quantification of Linear Olefin Isomers by Online Ozonolysis-Single Photon Ionization Time-of-Flight Mass Spectrometry

“…Gas chromatography (GC), a common off-line analysis method, can only resolve the terminal double bond in the carbon chain. It cannot identify the positions of all double bonds without prior derivatization such as ozonolysis [7]. Recently, the technical advances in mass spectrometry (MS) [8], especially new ionization methods such as matrix-assisted laser desorption/ ionization (MALDI) [9] and electrospray ionization (ESI) [10], and multistage MS [11][12][13] have become powerful tools in overcoming the above mentioned difficulties.…”
