EC number: 500-051-3
CAS number: 26780-96-1
Based on the estimated pKa-range (4.2- 5.0) under environmental conditions (pH 5 - 9) this substance is mainly present in undissociated form (Currenta, 2010).
According to QSAR estimation, this substance does not have a significant
dissociation at pH 5 - 9, and hence this estimate can be used for
chemical safety assessment. On the other hand TMQ is mostly insoluble
and it is scientifically very difficult to perform a test due to the
lack of sensitive analytical method.
