- Executive summary:
By dynamic effusion method with a micro-balance vapour pressure for 2 -amino-5-chloro-N,3-dimethylbenzamide was evaluated according to OECD guideline 104 (2006) and EC A.4 (2009).
The vapour pressure (P) of the test item extrapolated is 1.0855 x 10-5 Pa at 20 °C and calculated at 2.6515 x 10-5 Pa at 25 °C.
The volatility (H) of the test item calculated at 20 °C is 7.7846 x 10-6 Pa.m3.mol-1.
