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.

Application

2,2-Dimethoxypropane may be used as an analytical standard for the determination of the analyte in biological samples by headspace gas chromatography-mass spectrometry (HS-GC/MS) technique.
