1,6-Hexanedithiol Chemical Properties,Usage,Production

Chemical Properties

clear colorless to slightly yellow liquid

Chemical Properties

1,6-Hexanedithiol has a fatty, meaty odor. FEMA indicates that total dithiol added to any food should not exceed 1.00 ppm.

Occurrence

Reported found in boiled beef.

Uses

1,6-Hexanedithiol is used in self-assembled monolayers (SAMs). It is used in synthetic rubber and food with spices. It is also used in Food Flavor, Tobacco Flavor, Blending edible flavors: Beef, poultry soup .

Uses

HDT can be used to functionalize molybdenum disulphide (MoS₂), which can be used as a two dimensional transition metal dichalcogenide (TMD) in electronics and optoelectronic devices. It forms a SAM on gallium arsenic (GaAs) doped cadmium sulfide (CdS) quantum dots (QDs), which can be used for biosensors and solar applications. It can also be used to immobilize gold nanoparticles (AuNPs) for potential usage in biomedical and bioanalytical applications.

Definition

ChEBI: 1,6-Hexanedithiol is an alkanethiol.

General Description

1,6-Hexanedithiol (HDT) is a long chained bi-functional alkanethiol with 6 carbon atoms structured in a zig-zag pattern, which forms a tetrahedral configuration. It forms a self-assembled monolayer (SAM) on a variety of substrates and immobilizes the surface atoms.
