Applications of 3,4-dimethylphenol:

It can react with ethyl cinnamates in trifluoroacetic acid to form the corresponding dihydrocoumarin derivatives.
Bromination of 3,4-dimethylphenol using bromine can lead to 6-bromo-3,4-dimethylphenol.
It can react with 1-fluoro-4-chloromethyl-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoro-borate) (Selectfluor^? F-TEDA-BF₄) to form 4-fluoro-3,4-dimethylcyclohexa-2,5-dienone.
