- Specific details on test material used for the study:
- Name Ferric citrate monohydrate
Batch no. 45882
Appearance red to brown solid powder
Composition Ferric Citrate
CAS No. 2338-05-8
Molecular formula C6H5FeO7
Expiry date 18 May 2019
Storage Room Temperature (20 ± 5 °C); Keep away from light - Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 343 °C
- Remarks on result:
- not determinable
- Conclusions:
- The determination of the melting and boiling point of Ferric citrate monohydrate was performed via DSC (differential scanning calorimetry).
Three events were detected.
All events are endothermic.
The results of the determination should be stated under these circumstances as followed:
The first event as dehydration range from 62.76 °C to 170.32 °C (335.91 K to 443.47 K)
The second event as melting range from 169.43 °C to 238.99 °C (442.58 K to 512.14K) with peak maximum of 198.28 °C (471.43 K) and 208.02 °C (481.17 K)
The third event as chemical reaction as 342.78 °C (615.93 K)
No boiling point could be determined under these test circumstances as the test substance decomposed after melting.
