EC number: 217-703-5 | CAS number: 1934-75-4
Density
Administrative data
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- not reported
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Remarks:
- In German. Data from this publication are part of the Gmelin Handbook of Inorganic and Organometallic Chemistry and thus considered sufficiently reliable.

Applicant's summary and conclusion
- Conclusions:
- The relative density (D20/4) of the test substance is 1.714.
- Executive summary:
In the publication by Huttner and Knappe (1930), which is also cited in the Gmelin Handbook of Inorganic and Organometallic Chemistry, the relative density of sodium dicyanoamide was determined via pycnometer measurement.
The relative density (D20/4) of sodium dicyanoamide was found to be 1.714.
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.
