Description of key information

The test Item 2-[(2-nitrophenyl)amino]ethanol started boiling at 241.2 °C (514.4 K) at normal pressure (98.29 kPa) according to the criteria described in the guideline.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
241.2 °C

Additional information

The determination of the boiling point of 2-[(2-nitrophenyl)amino]ethanol was performed by visual judgement using the capillary method (Siwoloboff method) following OCDE guideline 103, EU Method A2 and GLP.

At about 255 °C in the preliminary tests, the number of air bubbles increased. To confirm the result obtained in the preliminary tests, the determination of the boiling point was performed three times, heating quickly up to 235 °C and afterwards slowly using a heating rate of 0.5 °C/min.

A clear normal boiling point, as defined in the guideline with a current stream of bubbles evolving from the capillary, was observed at a heating temperature of 241.2 °C (514.4 K).

This Boiling point test is classified as acceptable, and satisfies the guideline requirements for the OECD 103 and EU Method A.2
