COMMENT: The chemical compound was chemically modified with N-methyl-N-trimethylsilyl-trifluoroacetamide (MSTFA) before GC-MS analysis. When it has two or more functional groups, this modification gave a mixture of the TMS derivatives having different number of TMS groups at different functional groups.
