It is one of two isomeric bromonaphthalenes, the other being 2-bromonaphthalene. Under normal conditions, the substance is a colorless liquid.
It is prepared by treatment of naphthalene with bromine:[1]
The compound exhibits many reactions typical of aryl bromides. Bromide can be displaced by cyanide to give the nitrile. It forms a Grignard reagent[2] and organolithium compound. 1-Lithionaphthalene can be further lithiated to give 1,8-dilithionaphthalene, a precursor to peri-naphthalene compounds.
Because of its high refractive index (1.656-1.659nD),[3] 1-bromonaphthalene is used as an embedding agent in microscopy and for determining the refraction of crystals.
The compound is also used as a precursor to various substituted derivatives of naphthalene.
