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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- temperature of decomposition (state purity)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1981
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- peer-reviewed
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: not reported
- Principles of method if other than guideline:
- The thermogravimetric studies were carried out in air on a Stanton thermobalance at a heating rate of 6°C per min, and the simultaneous TG-DTA studies were made in an argon atmosphere on a Mettler thermal analyzer at a heating rate of 4°C per min.
- GLP compliance:
- no
- Type of method:
- differential thermal analysis
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 275 - <= 325 °C
- Conclusions:
- The boiling point of Guanidinium nitrate can not be determined. The substance starts losing weight at 230°C and the decomposition is fast between 275- 325°C. The weight loss is found to be sluggish in the temperature range 325-500°C.
No residue was left behind at 500°C which suggests that the entire mass has been converted into gaseous products. - Executive summary:
The boiling point of Guanidinium nitrate can not be determined. The substance starts losing weight at 230°C and the decomposition is fast between 275- 325°C. The weight loss is found to be sluggish in the temperature range 325-500°C. No residue was left behind at 500°C which suggests that the entire mass has been converted into gaseous products.
No expothermal reaction shows at temperature below about 200 °C

Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 230 °C
Additional information
The boiling point of Guanidinium nitrate can not be determined. The substance starts losing weight at 230°C and the decomposition is fast between 275- 325°C. The weight loss is found to be sluggish in the temperature range 325-500°C. No residue was left behind at 500°C which suggests that the entire mass has been converted into gaseous products (Udapa, 1982).
