2-Naphthalenethiol Chemical Properties,Usage,Production
Description
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.
Chemical Properties
2-Naphthyl mercaptan has a disagreeable sulfurous, mushroom, meaty odor
Chemical Properties
Almost white to cream powder
Uses
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.
Preparation
By catalytic hydrogenation of a sulfonic acid derivative of naphthalene; by reduction of naphthalenesulfonyl chloride with zinc.
Definition
ChEBI: 2-Naphthalenethiol is a member of naphthalenes.
Taste threshold values
Taste characteristics at 10 ppm: sulfurous, meaty, brown, roasted, chicken, eggy with a slight nutty nuance

General Description
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.
Safety Profile
Poison by ingestion and intraperitoneal routes. A mosquito larvicide. When heated to decomposition it emits highly toxic fumes of SOx.
Purification Methods
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.]
