Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
4-Amino-m-cresol started melting and became dark for a possible decomposition at 172°C. The sample was completely dark and decomposed at 178-180°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 172 °C
Additional information
The boiling point of 4-Amino-m-cresol was evaluated by following OECD guideline 102 (Melting point / Melting Range).
An aliquot of the dry sample was put into capillary tube, fused at one end, so that the filling level was approx. 3 mm after being tightly packed. The filled capillary tube was placed in the bath and heated under stirring so that the temperature increase was approx. 3°C/min. At about 10°C below the expected melting temperature, the rate of the temperature was adjusted to a maximum of 1°C/min. The initial and final melting temperatures were determined and recorded.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
