Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusions:
A specific gravity value of 1390-1450 kg/m³ for a 50% aqueous solution of ATMP-5Na was reported in a company MSDS. The original reference was not available for review and no further information is available. The reliability of this result is not assignable.

Description of key information

Density [ATMP-xNa]: The weight of evidence from company data is for specific gravity values in the range ca. 1.3 - 1.5 g/cm³ at ambient conditions for various commercial solutions.

Key value for chemical safety assessment

Additional information

No relative density of solid values are available, but this does not constitute a data gap since no solid ATMP-xNa products are known. A number of specific gravity values of individual commercial products are known for the aqueous solution of sodium salt of ATMP. While the individual sources are secondary literature, meaning that in most cases the reliabilities are not assignable, overall the weight of evidence is taken to be adequately reliable for the purpose of registration.

The following company data of non-assignable reliability are available:

1) A specific gravity of 1.4 g/cm³ at 20°C was reported for ATMP-3Na in online product literature for a major European producer. The original reference was not available for review and no further information is available.

2) A typical specific gravity of 1390 to 1450 kg/m3 at 20°C was reported for ATMP-5Na in a company product data sheet for a major European importer. The original reference was not available for review and no further information is available.
