Surface tension:
In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. The Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-,sodium(CAS no. 90294-36-3) is used as a laboratory chemical, Synthesis of substances, etc. For this use, surface activity is not an important property. Hence this study was considered for waiver.
Flash point:
Based on the Calculation done using scientifically verified and validated formulas / equations, the flash point of chemical 5-acetamido-2-aminobenzenesulphonic acid was estimated to be 280.694 degree C.
Autoflammability:
5-acetamido-2-aminobenzenesulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 5-acetamido-2-aminobenzenesulphonic acid is not auto-flammable.
Flammability:
5-acetamido-2-aminobenzenesulphonic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 5-acetamido-2-aminobenzenesulphonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 5-acetamido-2-aminobenzenesulphonic acid was considered non-flammable for chemical safety assessment.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
Oxidising properties:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
