- other: No other detail available
- Interpretation of results:
- other: Non-flammable
- Conclusions:
- The flash point of 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol(CAS No. 85-83-6) is 289°C at 976.3hPa.
- Executive summary:
The flash point determination of 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol (CAS No. 85-83- 6)was done following closed cup method using Pensky-Martens flash point apparatus.The test item started giving brown coloured fumes with burning smell at 289 °C. Thus, the flash point of test item was inferred to be greater than 289 °C at 976.3hPa.
The chemical 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol (CAS No. 85-83 -6) is reported to have flash point of >289 degree C. This high flash point suggests that the chemical will be non-flammable.

Description of key information
The flash point determination of 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol (CAS No. 85-83- 6)was done following closed cup method using Pensky-Martens flash point apparatus.The test item started giving brown coloured fumes with burning smell at 289 °C. Thus, the flash point of test item was inferred to be greater than 289 °C at 976.3hPa.
The chemical 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol (CAS No. 85-83 -6) is reported to have flash point of 289 degree C. This high flash point suggests that the chemical will be non-flammable
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 289 °C
Additional information
The flash point determination of 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol (CAS No. 85-83- 6) was done following closed cup method using Pensky-Martens flash point apparatus.The test item started giving brown coloured fumes with burning smell at 289 °C. Thus, the flash point of test item was inferred to be greater than 289 °C at 976.3hPa.
As per the available data for flash point from laboratory, the flash point value determined was 289 degree C. As the data from laboratory has K1 reliability thus considered as key study for the chemical safety assessment. Also based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance 1-(2-methyl-4-(2-methylphenylazo)phenylazo)-2-naphthol (CAS No. 85-83 -6) was considered to be non-flammable.
