Abstract

Electrospray mass spectrometIy has aided the structural characterization of ecdysteroid moulting hormones as a means of understanding factors controlling the moulting cycle in crabs. Possible fragmentation routes were frrst obtained by controlled collision‐activated dissociation (CAD) initiated by cone voltage fragmentation. Low energy CAD MSIMS analyses of the protonated molecules [M+H]+ confrrmed the characteristic fmgerprint patterns obtained by cone voltage fragmentation. MSIMS analyses of selected intermediate fragments provided additional structural data and established the fragmentation routes.
