Key result
Atm. press.:
101.325 kPa
Remarks on result:
not determinable
Remarks:
The boiling point of the test sample was not observed.

The first test:

- sample amount: 3.15 mg

- crucible: Aluminum, lid with a 50 μm hole

- heating rate: 5 °C/min

- temperature range: 30-500 °C

- atmosphere: N2 flow, 20 mL/min

 

The second test:

- sample amount: 3.27 mg

- crucible: Aluminum, lid with a 50 μm hole

- heating rate: 5 °C/min

- temperature range: 30-500 °C

- atmosphere: N2 flow, 20 mL/min

In both DSC tests, no thermal effects were detected except for the melting point; boiling point was not observed.

Conclusions:
The DSC test shows no thermal effects, except for the melting point. Therefore, the boiling temperature of Formononetin was not observed.

Description of key information

According to test method A.2 and OECD 103, the boiling temperature of Formononetin was not observed. The DSC test showed no thermal effects except for the melting point.

Key value for chemical safety assessment
