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)

Thymine residues in an oligodeoxyribonucleotide are subject to methylation at N3 by the internucleotide methyl phosphotriester linkages. This alkylation occurs most rapidly in the presence of a strong base such as DBU, but also takes place, at a much slower

Phosphate esters are important compounds in living systems. Their biological reactions with alcohol and thiol nucleophiles are catalyzed by a large superfamily of phosphatase enzymes. However, very little is known about the intrinsic reactivity of these nucleophiles with phosphorus centers.
