Description of key information
Additional information
The test item is a crystalline solid at room temperature with a melting point of 146 -147°C after recrystallisation from isopropanol.
The test item is reported to have a relative density of 1.34 with temperature of determination of density not reported.
The test item is an organic salt that cannot evaporate without decomposition.
The dissociation constant of the test item was determined as pK = 6.05.
The test item is marketed as an aqueous solution at a concentration of about 80% by weight and not used as a pure, solid substance.
The surface tension of an aqueous solution of the test item was determined as 71.67 mN/m (0.993 g/l). Therefore the test item is not considered as surfactant.
The viscosity of the test item was determined as 33.1 mPa*s at 20°C.
Calculations with EPIWIN (v4.00) gave the following results for the test item:
Vapour pressure = 0.00000446 Pa;
log Kow = -9.8.
The test item is considered not to be flammable because it is handled as an aqueous solution.
The test item does not contain any structural elements that are indicative of explosive or oxidising properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
