Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
EDTN (ethylenediaminetetraacetonitrile) has no physical/chemical properties that require classification.
The industrial product consists of white organic wet crystals with 10% water.
The dried substance is an offwhite organic powder, only used for analytical purposes.
The melting point is 130°C.
The substance starts to decompose before boiling at 180°C.
The relative density of the dried substance is 1.264
The particle size distribution on dried product is: d10: 60 µm, d50: 124 µm and d90: 221 µm; amount < 10 µm: 1% and amount < 100 µm: 35%.
The vapour pressure is low, below 4.20×10 -4 Pa (<3.15×10 -6 torr) at 25°C.
The Pow is < 1 (Log Pow < 0), so no bioaccumulation is expected.
At pH 5, 7, and 9, the water solubility is 304, 299, and 327 mg/L, respectively, at 20°C, so the substance is moderately soluble.
No surface activity is expected, because of molecular structure: ther is no hydrophobic tail.
The substance is not autoflammable, not flammable, has no explosive, oxidising or self heating properties (in addition, the industrial product consists of 10% water).
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.
