Molecular Structure



2,2-Dimethoxypropane or acetone dimethyl acetal or DMP is an organic compound and an alkylating reagent. 2,2-Dimethoxypropane is a reagent for the preparation of 1,2-diols as acetonides. It is the acetalisation product of acetone and methanol. Dimethoxypropane is an intermediate for the synthesis of 2-methoxypropene. DMP is commonly used as a water scavenger in water-sensitive reactions — any available water will react with DMP to form acetone and methanol.
