| Application: | Perchloric acid has been used to deactivate chloramine-T during the spectrophotometric determination of collagen content of the rat tibialis anterior (TA) tendons and tendon constructs. It also may be used in the following studies: • Determination of reduced glutathione (GSH) and oxidized glutathione (GSSG) content in liver tissues by high performance liquid chromatography (HPLC). • As an oxidizing agent in the estimation of sulfur (S) in plant samples. • As a solvent for the dissolution of plutonium. |
| General description: | Perchloric acid (HClO4), an oxygen acid of chlorine, is strongly acidic in nature. Hydrates of perchloric acid are obtained on its dissolution in water. |
