Description of key information
Waiver: hydrolysis testing is not required since pyridine has been shown to be readily biodegradable.
Key value for chemical safety assessment
Additional information
According to Regulation (EC) No.1907/2006, Annex VIII, Section 9.2.2.1, Column 2, hydrolysis testing as a function of pH does not need to be conducted if the substance is readily biodegradable. Pyridine has been shown to be readily biodegradable in the environment, as shown by the 91% DOC removal in 19 days in the Guideline 301A test conducted by Gerike and Fischer (1979), although this test did not specifically show that pyridine biodegradation met the criterion for 70% DOC removal within the 10-day window for ready biodegradability.
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.
