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. |
