General description
Trimethyl phosphate is an excellent dipolar aprotic solvent that is used as a methylating agent and acid scavenger in many organic transformations.
Application
Trimethyl phosphate can be used as a methylating agent for the:
- Solvent-free o-methylation of phenolic compounds to synthesize methyl aryl ethers.
- S-methylation of aryl/alkyl thiols to synthesize S-methylated product in the presence of Ca(OH)2 as a base.

An analytical method for the determination of 14 organophosphorus flame retardants (OPFRs), including halogenated OPFRs, non-halogenated OPFRs and triphenyl phosphine oxide (TPPO) in biological samples was developed using gas chromatography-mass spectrometry (GC/MS). Biological samples were extracted using microwave-assisted extraction (MAE)
