8-Hydroxyquinoline sulfate(Cas 134-31-6) Usage

Manufacturing Process

The mixture of 1.4 kg o-nitrophenol, 2.1 kg o-aminophenol, 6 kg glycerine (d = 1.26) and 5 kg sulfuric acid (d = 1.848) was heated at reflux to temperature 130°-140°C. This temperature was kept for 1.5 hours. The obtained oxyquinoline precipitated, the liquid was removed with water-steam distillation. The residue was diluted with water and alkalized with sodium hydroxide and sodium carbonate to the strong alkaline reaction. The repeated distillation with water steam gave the oil, which hardened as the long needles by cooling. MP: 75°-76°C recrystallized from diluted ethanol. In practice it is usually used as sulfate salt

Therapeutic Function

Antiseptic

Air & Water Reactions

Water soluble.

Reactivity Profile

A sulfate acidic salt of an amine that is also a phenol. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Fire Hazard

Flash point data for 8-Hydroxyquinoline sulfate are not available, but 8-Hydroxyquinoline sulfate is probably combustible.

Flammability and Explosibility

Notclassified

Metabolic pathway

Little published information is available.

Degradation

The salt and free base of 8-hydroxyquinoline sulfate are very stable but alkali liberates quinolin-8-ol which precipitates heavy metals (PM). 8-Hydroxyquinoline is a chelate ligand of transition metals such as copper.

General Description

Pale yellow to yellow crystalline powder with a slight saffron odor. Burning taste.
