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.

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.
