Trimethylsilyl diazomethane, used for methylation of OH-PBDEs, was obtained from Sigma-Aldrich (St.
Diazomethane was prepared from Aldrich Diazalid by normal procedures.
You read in the literature that it's a safe alternative to diazomethane because it's less explosive," Murphy says.
After saturation with hydrogen chloride, double methylation with acidified methanol and diazomethane was introduced.
Methyl esters were prepared using diazomethane in diethyl ether, and analysed by gas chromatography.

The purified extract was methylated using diazomethane and analysed using high-resolution gas chromatography.
The extract was concentrated to near dryness and derivatized with diazomethane to form the methyl ether of PCP.
The combined organic extracts were evaporated, and the residue was dissolved in 100 [micro]L of methanol and derivatized with 100 [micro]L of an ethereal diazomethane solution for 10 min at room temperature (2).
