Melting point:
According to ChemSafe 2009 3-chloro-p-toluidine melts at 24 °C (ChemSafe 2009).

Boiling point:
3-chloro-p-toluidine gives a boiling point of 243 °C at 1013 hPa (Lide 2001).

Density:
3-chloro-p-toluidine gives a bulk density of 1.17 g/cm3 (ChemSafe 2009).
Particle size distribution:
In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as the substance is marketed or used in a non solid or granular form.

Vapour pressure:
Calculated vapour pressure of 3-chloro-p-toluidine equals 0.0527 hPa, calculated for 25 °C (Currenta 2022).

Partition coefficient:
Calculated Partition Coefficient of 2-chloro-4-toluidine equals 2.27 (Currenta 2022).

Water solubility:
Water solubility of 3-chloro-p-toluidine was determined to be 2650 mg/L at 20 °C, pH was not given in this assessment. Since dissociated substance usually shows a (slightly) increased water solubility, causing an elevated exposure to aquatic organisms, water solubility should be determined with temperature and pH. However, derived from a pKa value of 3.9 it may be assumed that most of the compound will not be dissociated at pH ranges in the environment. Thus, water solubility of the compund is not significantly underestimated (Bayer 1987).

Surface tension:
In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as based on structure, surface activity of the substance is not expected.

Flash point:
The test item 2-Chloro-4-aminotoluene has a flash point of 88.5 °C at 1013 hPa (average corrected and rounded down to the nearest multiple of 0.5 °C, Consilab 2022) according to Regulation (EC) No 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2016).
Auto flammability:
The test item 2-Chlor-4-toluidin has an auto-ignition temperature of 600 °C according to the Regulation (EC) No 440/2008 Method A. 15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Testing of mineral oil hydrocarbons — Determination of ignition temperature.

Flammability:
In contact with water: the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied.
Flammability: the study does not need to be conducted because the substance is a liquid.
Self-heating: the study does not need to be conducted because the substance is completely molten at 160°C.
