Dolichols, polyprenols and their phosphates have been investigated by fast atom bombardment mass spectrometry and suitable matrices and doping conditions have been developed. The molar response decreases with the molecular weight. The sensitivity is much higher for the phosphates, which are already in the ionized form, than for the parent alcohols. All derivatives give rise to pseudo‐molecular ions. The polyprenols also gave rise to [M ‐ 18 + H] + ions and the phosphates produced fragment ions by elimination of [(C 5 H 8 ) n + 2].
