Description of key information
Relative density (ATMP-N-Oxide-5K): 1.444 at 20°C (OECD 109)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.444
Additional information
A relative density value of 1.444 at 20°C was determined for the aqueous solution of ATMP-N-Oxide-5K using a pycnometer method in accordance with OECD Test Guideline 109. The result is considered to be reliable and is selected as key study.
In available secondary sources to which reliability could not be assigned, density/specific gravity values are reported for ATMP-N-Oxide-5K as follows:
1) A typical density of 1.38 - 1.44 g/cm3 at 20°C was reported for ATMP-N-Oxide-5K in company safety data sheets of major suppliers in the EU. The original reference was not available for review and no further information is available.
2) A specific gravity of 1.44 g/cm3 at 20°C was reported for ATMP-N-Oxide-5K in a company product data sheet. The original reference was not available for review and no further information is available.
3) A specific gravity/density of 1.40 ± 0.02 g/cm3 at 25°C was reported for ATMP-N-Oxide-5K in a company safety data sheet. The original reference was not available for review and no further information is available.
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).
