Thiosalicylic acid Usage And Synthesis

Chemical Properties

white to light yellow crystal powder

Chemical Properties

Thiosalicylic acid, (o-mercapto benzoic acid), a sulfur-yellow solid that softens at 158 °C (316 °F), has a melting point of 164 °C (327 °F). It sublimes, is slightly soluble in hot water but freely soluble in glacial acetic acid and alcohol, and yields dithiosalicylic acid, upon exposure to air.

Uses

A trapping agent used in the desulfenylation of 3-indolyl sulfides

Uses

Trapping agent used in the desulfenylation of 3-indolyl sulfides.1 Condenses with diamines to form macrocyclic diamides.2

Uses

Thiosalicylic acid can be used as trapping agent in the desulfenylation of 3-indolyl sulfides and used to condense with diamines to form macrocyclic diamides.

Definition

ChEBI: A sulfanylbenzoic acid that is the 2-sulfanyl derivative of benzoic acid.

Purification Methods

Crystallise the thio acid from hot EtOH (4mL/g), after adding hot distilled water (8mL/g) and boiling with charcoal. The hot solution is filtered, cooled, the solid is collected and dried in vacuo (P2O5). Crystallise it from AcOH and sublime in vacuo.[Beilstein 10 IV 272.]
