N,N-Dimethylacetamide dimethyl acetal is used as a reagent for the synthesis of amides, diacylamines, and heterocycles, one carbon inserting synthon in preparation of pyrimido[1,2-a][1,3,5]triazin-6-ones. It is used as intermediate in building block.

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.
