Additional information

For the purpose of some experimental studies the solid form was used. In accordance with REACH Regulation, Art. 3, and ECHA "Guidance for identification and naming of substances under REACH and CLP" v2.1, May 2017, substances have to be separated from solvents if this is not affecting the stability of the substance or changing its composition.

For this purpose the solvent (water) was removed under difficult conditions. However, Bayscript Blaukomponente TEA-Salz is marketed in liquid form.
