Additional information

Using the HPLC method according to OECD 121 or EU C.3 respectively, the retention time of Norbornene on a cyanopropyl chemical bound resin on a silica base column was determined in comparison to six reference compounds. Methanol/Water =55:45 was used as eluent. Measurements of the reference mixture were repeated 3 times each before and after the substance sample. The substance sample again was measured three times.

the log Koc determined for Norbornene (main peak) was 2.273 +/-0.001.
