Description of key information
Additional information
Sulfadimidine is white or yellowish white powder at 101325 Pa and 20 °C.
The experimental melting point of the substance is 198.5 °C at atmospheric pressure.
No experimental data regarding boiling point of the substance are available but a predicted boiling point of 451.19 °C is calculated by EPI Suite v.4.1
The estimated vapour pressure for this substance is 6.82*10-9 mmHg at T= 25°C.
The experimental logKow of Sulfadimidine is 0.19 and it is soluble or slightly soluble in water (1500 mg/l at T= 29°C with increasing of solubility with the increasing of pH). Sulfadimidine is soluble in acetone, ether and it is slightly soluble in alcohol.
Surface tension is not expected for this substance.
Flash point is waived based on solid nature of Sulfadimidine.
The substance is not explosive and it hasn't got oxidising properties.
The dissociation constants for Sulfadimidine are pKa1 = 2.65 (aromatic amine) and pKa2 = 7.65 (sulfonamide nitrogen).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
