Specific details on test material used for the study:
- Name of test material (as cited in study report): Piperazine citrate / tripiperazine dicitrate- Molecular formula: C12H30N6•Cl2H16O14 - Molecular weight: 642.76 g/mole - Substance type: Organic - Physical state: Solid
Key result
Boiling pt.:
208 °C
Atm. press.:
976.5 hPa
Decomposition:
yes
Decomp. temp.:
220 °C
Remarks on result:
other: The test item showed foam formation at 208 °C and colour changed from white to dark brown at 220 °C

The test was conducted in replicates and the test itemshowed foam formation at 208 °C and colour changed from white to dark brown from 220 °C. Thus, the decomposition temperature was inferred to be 220°C at 976.5 hPa.

Conclusions:
The boiling point determination of Test item Tripiperazine dicitrate (CAS No. 144-29-6) was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The test item started to boil and showed foam formation at 208 °C and colour changed from white to dark brown from 220 °C. Thus, the decomposition temperature was inferred to be 220°C at 976.5 hPa.
Executive summary:

The boiling point determination of Test itemTripiperazine dicitrate(CAS No. 144-29-6) was done as per the test guideline OECD 103. The method followed was according toSiwoloboff. The test item started to boil and showed foam formation at 208 °C and colour changed from white to dark brown from 220 °C. Thus, the decomposition temperature was inferred to be 220°C at 976.5 hPa.
