2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) crystalline solid with the formula C 10 H 7 OH. It is an isomer of 1-naphthol , differing by the location of the hydroxyl group on the naphthalene ring.
2-Methoxynaphthalene, also called β-naphthol methyl ether or yara yara, [2] is a stabilizer found in gunpowder, particularly smokeless gunpowders. It is soluble in alcohol , and insoluble in water and dipropylene glycol .
1-Nitroso-2-naphthol can be prepared by treatment of 2-naphthol with nitrous acid: [3] C 10 H 7 OH + HNO 2 → C 10 H 6 (NO)OH + H 2 O. Its conjugate base forms deeply colored complexes with iron(II) and cobalt(II), complexes [M(C 10 H 6 (NO)O) 3] 2-. [4] The deep colors of these complexes results from the delocalized bonding within each five ...

2-Naphthylamine or 2-aminonaphthalene is one of two isomeric aminonaphthalenes, compounds with the formula C 10 H 7 NH 2. It is a colorless solid, but samples take on a reddish color in air because of oxidation. It was formerly used to make azo dyes, but it is a known carcinogen and has largely been replaced by less toxic compounds. [2]

2-Naphthalenethiol is prepared from 2-naphthol by the Newman–Kwart rearrangement starting from a thiocarbamate. [1] It undergoes lithiation at the 1 and 3-position. [2] [3] It can be used as a flavouring agent and has been described as having an “artichoke”, “meaty” and “creamy” taste”. [4] [5]
