Test material

Constituent 1
Chemical structure
Reference substance name:
2,3,4,9-tetrahydro-1H-carbazol-3-one
EC Number:
610-619-3
Cas Number:
51145-61-0
Molecular formula:
C12H11NO

Results and discussion

Boiling point
Boiling pt.:
> 320 °C
Decomposition:
yes
Decomp. temp.:
137 - 154.5 °C
Remarks on result:
other: In duplicate tests, the test material did not boil below the maximum operating temperature of the equipment (approx. 320 °C). There was a possibility that the material decomposed on melting, as indicated by a colour change (Reference Section 4.2)
