1-NAPHTHALENETHIOL Structural

What is 1-NAPHTHALENETHIOL?

Chemical properties

clear light yellow to yellow liquid

The Uses of 1-NAPHTHALENETHIOL

1-Thionaphthol is used to produce the di-[1]naphthyl disulfide. It is also used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.

The Uses of 1-NAPHTHALENETHIOL

1-NAT can be used as a model analyte to characterize the performance of the surface enhanced raman scattering (SERS).

General Description

1-Naphthalenethiol (1-NAT) is a standard analyte that can be diffused in the polymeric network for the detection of optical properties.

Purification Methods

It is steam volatile and is purified by distillation in the absence of O2, as it oxidises to the disulfide. It is soluble in Et2O and EtOH but very slightly soluble in H2O and dilute alkalis. The S-ethyl derivative, [17539-31-0] M 188.2, has b 175-176o/25mm, and do 1.120. [Beilstein 6 III 2943, 6 IV 4241.]
