The following pages present experimental mass spectra of all known and suspect alkyl phosphates discussed in the manuscript

Triethyl phosphate

Fig. S1: The following are the mass spectra of known and suspect alkyl phosphates from 35-250 m/z (due to high fragmentation, ions were not present above 250). m/z 99 common among trialkyl phosphates. m/z 127 and/or 155 are often exhibited.

Tripropyl phosphate

Tributyl phosphate

Fig. S2: Dialkyl phosphate TMS esters exhibit a major peak at m/z 155 and/or 171 and a minor peak at ion 77.
