m-Cresol, also 3-methylphenol, is a phenol, with formula (CH3)C6H4(OH).
Amongst its uses it can be used as a solvent for dissolving polymers, most notably the conducting polymer polyaniline. When polyaniline is cast from a solution of m-cresol or a polyaniline film is exposed to m-cresol vapor the conductivity is higher than a polyaniline film cast without the presence of m-cresol.
It is an isomer of p-cresol, o-cresol and anisole
For more information see cresol.
