What is 2,2-Dimethoxypropane?
Chemical properties
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.
The Uses of 2,2-Dimethoxypropane
2,2-Dimethoxypropane(DMP) is used in histology and considered to be more efficient than ethanol for the dehydration of animal tissue.
The Uses of 2,2-Dimethoxypropane
2,2-Dimethoxypropane acts as a dehydrating agent. It also serves as an intermediate in the synthesis of vitamin E, vitamin A and various carotenoids such as astaxanthin. It is used as a reagent for the preparation of 1,2-diols, acetonides, isopropylidene derivatives of sugars, nucleosides, methyl esters of amino acids and enol ethers.
What are the applications of Application
2,2-Dimethoxypropane is a starting material and efficient tissue dehydration agent
General Description
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.
