molecular weight of the compoundwas deduced to be m/z 1,007 from the fast atom bombardment
MS(FAB-MS) of the cluster ions of mulundocandin with lithium and sodium. Thus in
the presence of lithium iodide in 3-nitrobenzyl alcohol matrix the [M+Li]+ peak appeared at m/z
1,014 and in the presence of sodium acetate in the same matrix the [M+Na]+peak was observed at
m/z 1,030. Without any additive to promote clustering the compound did not exhibit the [M+H]+
peaKas memostaounaantpeaKaue to extensive
loss of H2O-the most intense peak was observed
at m/z 990 and in addition, an
