Descrição geral

Trimethyl phosphate is an excellent dipolar aprotic solvent that is used as a methylating agent and acid scavenger in many organic transformations.

Aplicação

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)

The transfer of 17O and/or 18O from (COOH-17O or -18O) enriched substrates to inorganic phosphate (Pi) has been demonstrated for two enzyme-catalyzed reactions involved in folate biosynthesis and glutamylation. COOH-18O-labeled folate, methotrexate, and dihydropteroate, in addition to [17O]-glutamate, were synthesized

Due to the neurotoxicity of organophosphate (OP) pesticides and nerve agents synthesized as military or terror agents, their safe destruction and disposal is of considerable current importance. A representative OP, trimethyl phosphate (TMP), was adsorbed onto NaX zeolite, two mesoporous
