Description of key information

Additional information

5-methoxy-2-methylsulphanilic acid is a white to grey powder at 101325 Pa and 20 °C.

No experimental data are available for the substance.

Estimated data were calculated by EPIWIN 4.1.:

- predicted melting point is 152.63 °C;

- predicted boiling point is 398.51 °C;

- predicted vapour pressure is 1.02 *10^-8 mmHg at T= 25°C;

- predicted partition coefficient n-octanol/water is -1.45 at T= 25°C;

- predicted water solubility is 6208 mg/l at 25°C

The density was calculated by ACD/Labs (1.4 g/cm^3 at 20°C).

Since it is a solid, properties like surface tension and flash point can be neglected.

5-methoxy-2-methylsulphanilic acid is not expected to be explosive and based on the known experience in the handling and use of substances it is not a strong oxidizing agent.
