- Endpoint:
- temperature of decomposition (state purity)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- no
- Type of method:

- Specific details on test material used for the study:
- Lot 201009MA2 solid
- Key result
- Atm. press.:
- ca. 166 Bar
- Decomposition:
- yes
- Decomp. temp.:
- ca. 348 °C
- Conclusions:
- The substance "By-product from Guanidinoacetic acid manufacturing" decomposes at 348 °C.
- Executive summary:
Approx. 2 g of substance were heated from 20 °C - 400 °C under isochoric conditions with a rate of 4,8 °C/min. Exothermia and increase in pressure should be determined.
Up to 400 °C exothermia could not be observed. The maximum pressure determined in this experiment was 166 bar at 348 °C. After cooling to 26 °C pressure was 140 bar.
The residue of the test substance was a black, charcoaled solid.
