Applications & Uses

Uses

2,7-Dimethoxynaphthalene was employed as matrix to investigate the structure of polymetallic porphyrins via matrix-assisted laser desorption/ionization. It was also used in the synthesis of:peri-aroylnaphthalene compounds via elective electrophilic aromatic aroylation2-amino-1,2,3,4-tetrahydronaphthalene-6,7-diol
