Β-Naphthol methyl ether explained

β-Naphthol methyl ether, also called 2-methoxynaphthalene or yara yara,^[1] is a stabilizer found in gunpowder, particularly smokeless gunpowders. It is soluble in alcohol, and insoluble in water and dipropylene glycol.

Studies have also been done on the antiinflammatory effect of β-naphthol methyl ether^[2] and on how it behaves in time-resolved resonance Raman studies.^[3]

Synthesis and uses

Nerolin can be prepared by alkylation of β-naphthol with dimethyl sulfate. It has a faint but persistent odor and used to be a scented compound found in soap and other products.^[4]
