During manufacturing process the hydrated form, sodium 2-biphenylate tetrahydrate (CAS no. 16252-33-6), is produced. According to REACH Annex V (6) the hydrated form is covered by the registration of the anhydrous form.

Only the hydrated form is produced, marketed and used. Therefore all physicochemical tests have been performed with the hydrated form.
