Description of key information
Additional information
The substance is a clear white to yellowish liquid. Amoniacal odour.
The boiling point of could not be determined due to decomposition. The substance remains a liquid to -25°C, thus, a melting point test was not performed.
The substance density was determined to be 0.848 g/mL (=848 g/L) @ 22.5 degrees.
Vapor Pressure @ 283.15 K is 133.3 Pa.
The substance is fully miscible in octanol and highly miscible in water.
Water solubility is high and estimated at 54990 mg/L.
The mean surface tension value is measured at 62.08±0.1 mN/m for a 1.015 g/L solution.
Flashpoint temperature was measured at 138°C (Pensky Martens). The substance is non-flammable and decomposes at temperatures above 175°C. The substance is not explosive, and is not oxidizing. It is stable under normal conditions.
pKa values were determined by modlelling using SPARC tool to be 9.69 and 9.41
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
