Description of key information

The flash point determination of 4-(phenylazo)benzene-1,3-diamine (CAS No. 495-54-5)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 213.3°C at 968.9hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
213.3 °C

Additional information

The flash point determination of 4-(phenylazo)benzene-1,3-diamine (CAS No. 495-54-5)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 213.3°C at 968.9hPa.

Other supporting data from secondary source also indicates the flash point of the test substance 4-(Phenylazo)benzene-1,3-diamine as 214.8°C, which supports the selected key value. Both these value indicates that the test substance is not flammable.
