说明

一般描述

Ammonium oxalate monohydrate is the diammonium salt of oxalic acid. Its refined crystal structure has been investigated by three-dimensional diffraction studies.[1] Influence of bivalent [Mn(II), Co(II), Ni(II)] and trivalent cations [Fe(III), Cr(III)] impurities on the growth rates of ammonium oxalate monohydrate crystals has been described.[2] Its space group and unit cell parameters have been analyzed by neutron diffraction studies.[3] Its IR spectra has been compared with that of isolated coal-solubilizing agent (CSA).[4]

应用

Ammonium oxalate monohydrate may be used to prepare an electrochemiluminescence (ECL) solution containing 1mM tris(2,2-bipyridyl)ruthenium(II) (Ru(bpy)₃²⁺) and 0.2mM ammonium oxalate monohydrate in a 0.1M ammonium acetate buffer at pH 5.0.[5]
