Application

Magnesium acetate tetrahydrate has been used in the fabrication of biotin-labeled DNA nanotubes.

General description

Magnesium acetate tetrahydrate is the hydrated magnesium salt of acetic acid. Its crystals are needle-shaped and monoclinic. In its molecule, magnesium atom is located at the center of symmetry and is surrounded by 4 water molecules, while the two acetate groups are located in plane. On thermal dehydration, it forms anhydrous glass, which exhibits the glass transition phenomenon around 470K.
