2-Ethyl-9,10-dimethoxyanthracene is reported to possess antihistaminic activity. Photoinduced electron transfer from the singlet excited state of 2-ethyl-9,10-dimethoxyanthracene to CCl4 has been reported. The photosensitized reductions of 4-cyanobenzylmethylphenyl sulfonium tetrafluoroborate by 2-ethyl-9,10-dimethoxyanthracene excited singlet state is reported to yield phenyl methyl sulfide. 2-Ethyl-9,10-dimethoxyanthracene (EDMA) has been reported as a potential anthracene photosensitizer for diaryliodonium and triarylsulfonium salts.
