(Rossberg et al.2006)
Oxidising properties: due to its chemical structure the active substance does not contain functional groups in its molecular backbone which are known to enhance oxidising properties. The atom chlorine, presented in the chemical structure, is only bonded to carbon. Thus the active substance may not react exothermically with a combustible material and does not have oxidising properties.
Stability in organic solvents and identity of relevant degradation products: in accordance with Annex IX of the Regulation EC 1907/2006 testing is not neccessary because the stability of the substance is considered not to be critical.
Dissociation constant: due to a lack of relevant functional groups, the dissociation constant is irrelevant.
Chlorobenzene's viscosity is 0. 756 mPa*s (Kirk-Othmer, 2006)
