Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
In aerobic mineral soils the half life of the substance was determined to be 34.78 days at 20 °C (normalised data below). In water sediment systems the half life of the substance was determined to be 0.9 days (0.8 days in the water phase only).
6-CPA was identified as the major degradate in both hydrolysis and photolysis. 6-CPA appears to degrade through hydroxylation (breaking the pyridine ring) and microbial mineralisation.
In addition the substance was shown to be mobile to moderately mobile in several soils, according to available mobility studies. The adsorption coefficient (Kd) for the substance ranged from 0.947 to 19.9 with Koc values ranging from 254 to 764, respectively. The major degradate 6-CPA is mobile in mineral soils and high organic matter soils, with approximate Kd values ranging from 0.387 (mineral soils) to 1.02 (high organic matter soils). The substance also has a high vapour pressure (0.37 Pa) and hence is prone to volatilise from the application site. Substance volatilisation from soil appears to be dependent on the depth of incorporation as well as air-flow rates and soil temperatures. Hence, the substance could move off site through leaching and volatilisation.
The BCF value of 85 L/kg wwt was determined in bluegill fish and therefore the substance is not bioaccumulative.
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.
