Conclusions 1. The cleavage of the second and third molecules of CH3OH fromβ- methyl-2,3,4,6-tetra-O-methyl-D-galactopyranoside under chemical ionization conditions occurs predominantly as the result of 1,2-elimination. 2. The formation of the fragments [M+H-2CH3OH]+ is accompanied by the cleavage of H from C2 (by 84%), while the formation of the ions [M + H − 3CH3OH]+ is accompanied by the cleavage of H from C2 and C5 (respectively by 86 and 90%).
