Description and Uses

Trimethyl phosphate is used as an intermediate in organic synthesis. Its industrial applications are much fewer than those of other organic phosphates.Trimethyl phosphate undergoes hydrolysis in contact with water, so it should be stored in a moisture-proof manner. Due to its hydrolysis and release of PO43-, thus becoming a homogeneous precipitant for the formation of insoluble phosphate precipitation, often used as a precipitation reagent for zirconium and hafnium and as a diffusion source for the determination of semiconductors. In addition, trimethyl phosphate is also a phospholipid extractant for the extraction and separation of certain metal ions.
