Surface tension:
The study does not need to be conducted because water solubility is below 1 mg/L at 20°C.
Flash point:
The study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids.
Auto flammability:
Hydrogen bis[3-[[1 -(3 -chlorophenyl)-4,5 -dihydro-3 -methyl-5 -oxo-1H-pyrazol-4 -yl]azo]-4 -hydroxy-N-methylbenzenesulphonamidato(2 -)]cobaltate(1 -) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that hydrogen bis[3 -[[1 -(3 -chlorophenyl)-4,5 -dihydro-3 -methyl-5 -oxo-1H-pyrazol-4 -yl]azo]-4 -hydroxy-N-methylbenzenesulphonamidato(2 -)]cobaltate(1 -) is not auto-flammable.

Thus it can be concluded that Hydrogen bis[3 -[[1 -(3 -chlorophenyl)-4,5 -dihydro-3 -methyl-5 -oxo-1H-pyrazol-4 -yl]azo]-4 -hydroxy-N-methylbenzenesulphonamidato(2 -)]cobaltate(1 -) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Hydrogen bis[3 -[[1 -(3 -chlorophenyl)-4,5 -dihydro-3 -methyl-5 -oxo-1H-pyrazol-4 -yl]azo]-4 -hydroxy-N-methylbenzenesulphonamidato(2 -)]cobaltate(1 -) was considered non-flammable.
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.
Oxidizing properties:
The study does not need to be conducted because the substance is a solid.
