用途有機合成原料。
用途2,2-ジメトキシプロパン (2,2-dimethoxypropane)、別名 アセトンジメチルアセタール (acetone dimethyl acetal) は、有機化合物のひとつ。DMP と略される。アセトンとメタノールが縮合したアセタールに相当する。メチル化剤、アセトニド化剤、アセタール合成のための脱水縮合剤として用いられる。 DMPは2-メトキシプロペン合成の中間体として現れる。組織学では、DMP は動物組織の脱水にあたりエタノールよりも有効と考えられている。
使用2,2-Dimethoxypropane(DMP) is used in histology and considered to be more efficient than ethanol for the dehydration of animal tissue.
一般的な説明2,2-Dimethoxypropane is an organic compound, which may be used as a protecting agent in the process of the synthesis of structurally related alkaloids like narciclasine and lycoricidine using phenylbromide as the starting material.

化学的特性colourless liquid; B.P. 83℃. Ethereal odor. Soluble in alcohol, miscible with ess, oils and perfume chemicals. Stable when pure and at room temp. Decomposes into Acetone and Methanol during heating in presence of moisture or traces of mineral acid. Presumably not used in flavors. Rarely used in perfumes - for ethereal top-notes and "alcohol-like" effects. Produced synthetically via orthoformic ester or vinyl ether. Also from formiminomethyl-ether hydrochloride.
