Application

m-Cresol can be used as a starting material to synthesize:
  • Thymol via isopropylation reaction with 2-propanol in the presence of an acid catalyst.[1]
  • Terpolymeric resin by an acid-catalyzed polycondensation reaction with hexamine and formaldehyde.
  • 4,7-Dimethylcoumarin via modified Pechmann condensation reaction with ethyl acetoacetate.
