| Notes | Samples were prepared as follows: Standards brought to dryness under nitrogen, then 50 µL BSTFA + 1% TMCS (cat.# 35606) were added. 50 µL pyridine was then added, and samples were incubated at 70 °C for 30 min. After incubation, samples were diluted with butyl chloride. * Cannabinol was used as a derivatization check. |
