Application

4-methoxyphenol may be used in the synthesis of butylated hydroxy anisoles via alkylation with methyl tert-butyl ether over a non-zeolitic solid acidic catalyst. This process is eco-friendly when compared to the Friedel-Crafts alkylation reaction. 4-MP may also react with aqueous nitrous acid to form 2-nitro-4-methoxyphenol and benzoquinone in varying ratios depending on the reaction conditions. 4-MP can be used as a building block in designing β-cyclodextrin 4-methoxyphenol conjugates that can be potential ligands for drug complexation.

In larval zebrafish, melanocyte stem cells (MSCs) are quiescent, but can be recruited to regenerate the larval pigment pattern following melanocyte ablation. Through pharmacological experiments, we found that inhibition of γ-aminobutyric acid (GABA)-A receptor function, specifically the GABA-A ρ subtype
