Applications

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.

Notes

Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong bases and strong oxidizing agents.
