Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
After evaporation or exposure to air, the substance will be rapidly degraded by photochemical processes with a half-life of 1.09 days. The substance is stable to hydrolysis as well in biological active systems under aerobic and anaerobic conditions like in soil and water/sediment systems. However, photodegradation in water could be an important route of dissipation . The substance degraded rapidly with half-lifes ranging from 2.5 to 5.3 days, at pH valued from 4 to 9 and 12 hours of irradiation. Major photodegradation products were Furo[3,4 -b]pyridin-5(7H)-one-7 -hydroxy- and 2,3 - Pyridinedicarboxylic acid accounting for 29.7 % and 22.7 % of applied radioactivity, respectively. In contrast to the photolysis in aqueous media, the photolytic degradaton of the substance on soil surface was slow. Accumulation of the substance in organisms is not to be expected based on the low determined BCF value (<1) which is in line with the low logPow (< 1.3). Due to the low Koc value of the substance (mean 65.2) adsorption to soil is not expected.
Additional information
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.
