Additional information

The distribution of m-cresol between aqueous solution and air is described by the Henry’s law constant.

A thermodynamic method was used to determine the Henry's law constant of m-cresol. At 25°C a value of 0.087 Pa*m³/mol was obtained. This value indicates a low volatility for m-cresol from aqueous solution.
