Description of key information

Hydrolysis

According to structural properties, hydrolysis in not expected/probable. According to literature data of Harris (1990), Kollig et al. (1993) and Boethling & Mackay (2000) hydrolysis of the substance is not expected.

Biodegradation in water: screening test

The ready biodegradability of the test substance was determined according to OECD 301 F "Ready Biodegradability: Manometric Respirometry Test" (reference 5.2.1-1). Within the study period of 28 days, a degradation of 2 - 3 % was determined for the test substance. Therefore, the test substance is considered to be not ready biodegradable.

Bioaccumulation: aquatic

The test item showed no relevant bioaccumulation. The steady state BCF values were at 145 and 180 (mean 163).

Adsorption/desorption

The log Koc of the test item was determined to be > 4.2. The Koc was calculated to be 15849 L/kg.
