Additional information
As per REACH Annex VII- column 2, the study on boiling point need not be conducted for substances which decompose before boiling. The boiling point of (3-Ammonio-4-methoxyphenyl)(2-hydroxyethyl)ammonium sulphate, according to Directive 92/69/EC Method A.2, could not be determined, since degradation was observed during determination of the melting point/melting range. The test substance was discoloured to dark brown. Degradation of test substance started at 417 K (144˚C) during the melting process.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
