Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Remarks on result:
other: relative density: 1.678

According to the reference, the density values can be assumed to refer to temperatures near room temperature. For this reason 20 °C was filled in as temperature.

The relative density was calculated from the value of the handbook. The value was divided by the relative density of water at 4 °C (1.000).

Conclusions:
According to the reference, the relative density of ammonium thiosulphate is 1.678 at approx. 20 °C.

Description of key information

Relative density of ammonium thiosulfate: 1.678 at approx. 20 °C.

Key value for chemical safety assessment

Relative density at 20C:
1.678

Additional information

For the evaluation of this endpoint data from one handbook (CRC handbook) were used as key information. Handbook data considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance". Useful reference books and data compilations containing peer reviewed physico-chemical data include the CRC Handbook of Chemistry and Physics.

Data from this handbook indicate that ammonium thiosulfate has a density of 1.678 g/cm³. According to the reference, the density value can be assumed to refer to temperatures near room temperature. For this reason 20 °C was entered as temperature.

The relative density was calculated from the value in the handbook. The value was divided by the relative density of water at 4 °C (1.000).
