Chemical Properties
off-white to light brown crystalline powder
Uses
2-Hydroxybenzothiazole may be employed as carbon, nitrogen and energy supplement in the bacterial cultures. It may be used in the preparation of insulating thin polymer (<0.1μm), via electropolymerization.
Definition
ChEBI: Benzothiazole substituted with a hydroxy group at the 2-position.

General Description
2-Hydroxybenzothiazole (2-OHBT) is a 2-substituted benzothiazole. It is a tautomer of 2-benzothiazolinone. Its enthalpy of formation in the gas phase has been determined using high-level ab initio molecular orbital calculations at the G3(MP2)//B3LYP level of theory. Polarized IR spectra of the hydrogen-bonded molecular crystals of 2-OHBT have been studied. Oxidation of 2-OHBT using H2O2/UV and iron(III) photoassisted Fenton techniques have been reported. 2-OHBT is released into wastewaters during the industrial production of 2-mercaptobenzothiazole, a rubber vulcanization accelerator. The anodic oxidation of 2-OHBT on copper, iron and platinum in alcohol and alcohol-water solutions by cyclic polarization and chronoamperometry has been reported.
Purification Methods
Crystallise it from aqueous EtOH or water. [Hoggarth J Chem Soc 3314 1949, Hunter J Chem Soc 135 1930, Beilstein 27 H 182, 27 I 270, 27 II 225, 27 III/IV 2693.]
