Trimethyl phosphate is used as a color inhibitor for polyester and other polymer preparations, flame retardants and plasticizer. It acts as a solvent for aromatic halogenations and nitration reactions. It is used as a mild methylating reagent which is used in the dimethylation of aniline and related heterocyclic compound. Furthermore, it is involved in the synthesis of 1-methyl-pyridinium; dimethyl phosphate by reacting with pyridine.
Alternative to dimethyl sulfate for preparation of methyl esters of hindered carboxylic acids: Chem. Ind. (London), 1002 (1973). Used in N,N-dimethylation of aromatic amines, avoiding quaternization: Org. Synth. Coll., 5, 1085 (1973), and in N-methylation of nitrogen heterocycles, e.g. pyrimidines and imidazoles: J. Chem. Soc., Perkin 1, 391, 2506 (1973).
