Additional information

The Partition Coefficient of 2-Methoxymethyl-p-phenylenediamine (MBB) was determined following the OECD 117 guideline (Partition Coefficient (n-octanol/water) using High Performance Liquid Chromatography (HPLC)).

The test was conducted with a test material concentration of 5 mg/L in mobile phase consisting of 66.6% methanol and 33.3% phosphate buffer. Samples of the test material were analyzed via HPLC on a C18 column with DAD-detection.

The Partition Coefficient (n-octanol/water), log Pow of 2-Methoxymethyl-p-phenylenediamine (extrapolated) was -0.649. The Pow was 0.224
