Description

2,2-Dimethoxypropane or acetone dimethyl acetal or DMP is an organic compound and an alkylating reagent. The chemical formula is C5H12O2 and the molecular formula is (CH3)2C(OCH3)2. It is the acetalisation product of acetone and methanol. Dimethoxypropane is an intermediate for the synthesis of 2-methoxypropene. In histology, DMP is now considered to be more efficient than ethanol for the dehydration of animal tissue.
DMP is commonly used as a water scavenger in water-sensitive reactions -- any available water will react with DMP to form acetone and methanol.
