Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The Shake flask method was used to measure the disappearance of 2-methylpyridine from samples of creosote-adapted inoculum. After 14 days no amount of 2-methylpyridine was detected resulting in 100% degradation. It was also found that by following the method described by Bunch and Chambers (1967) that 2-methylpyridine was biodegraded. Under sulfate-reducing conditions, < 8% of 2-methylpyridine remained after 8 months; however, under methanogenic conditions 97% of 2-methylpyridine remained after 8 months. In another study degradation was not reported, as 2-methylpyridine was persistent in an anoxic sediment (the sediment (<1mm, sieved) and overlying water (pH 7.48, salinity 13%, sulfate concentration 13.5mM) water was collected from the estuary of the Tansui River (Guandu, Taipei).
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.
