2-Naphthalenthiol has a disagreeable mercaptan-like odor. May be prepared by catalytic hydrogenation of a sulfonic acid derivative of naphthalene; by reduction of naphthalenesulfonyl chloride with zinc.
Almost white to cream powder
2-Naphthyl mercaptan has a disagreeable sulfurous, mushroom, meaty odor
2-Thionaphthol was used in the preparation of cholesterol monolayer and multilayer Langmuir- Blodgett (LB) films. The magnetic resonance shift for a self-assembled monolayer of 2-naphthalenethiol was studied that suggested considerable promise in flexible and transparent photonic devices for biological and chemical sensing.

ChEBI: 2-Naphthalenethiol is a member of naphthalenes.
Taste characteristics at 10 ppm: sulfurous, meaty, brown, roasted, chicken, eggy with a slight nutty nuance

Poison by ingestion and
intraperitoneal routes. A mosquito larvicide.
When heated to decomposition it emits
highly toxic fumes of SOx.
It is steam volatile. It has to be distilled under Ar or N2, as it oxidises to the disulfide, and crystallises from EtOH. The S-methyl derivative has m 104-105o (from *C6H6/pet ether), and the S-ethyl derivative M 188.2, has m 16o and b 175-170.5o/15mm. The S-acetate has m 53.5o and b 191o/15mm, and the diethylamine salt forms yellow needles m 107o from dioxane. [Beilstein 6 H 657, 6 I 316, 6 II 610, 6 III 3006, 6 IV 4312.]
