Description

1,3-Dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone is a versatile solvent used in the N-alkylation of chiral and O-alkylation of aldoses. It is involved in the preparation of poly(aryl ethers). It is a cyclic urea and used as a polar aprotic organic solvent. Further, it reacts with trifluoro-methanesulfonic acid anhydride to prepare 2,2'-oxy-bis(1,3-dimethyl-tetrahydropyrimidinium) bis(trifluoromethanesulfonate).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
