Additional information

One key study according to the OECD draft document TGP/9475 and the requirements of the Annex to European Commission Directive 92/69/EEC to GLP is available. An attempt was made to determine the log Koc experimentally using HPLC. However no well defined response for the test substance was obtained and the log Koc was estimated using a PC KOC computer program, Version 1.21, Syracuse Research Corporation. The estimated Log10Koc was 1.80 and the equivalent Koc was 63.1.
