Perchloric acid

Perchloric acid (CAS 7601-90-3), formula HClO4, is a strong inorganic acid and powerful oxidizing agent.

Where is Perchloric acid used?

• Mining and metals processing: digesting refractory ores
• Electronics: etching and surface preparation with precise metal removal
• Pharmaceutical and chemical laboratories: ion-pairing reagent in HPLC and catalyst in organic synthesis
• Water treatment: pH adjustment and preparation of perchlorate-based reference standards
• It dissolves resistant metal matrices and drives specific oxidation reactions under controlled conditions.

Good to know: Technical and reagent grades exist alongside high-purity analytical grades meeting specifications for laboratory and pharmaceutical use. Availability depends on the specific grade and regional regulatory requirements.

Commercial specifications

• Aqueous solution at 70% and 60% concentrations
• Packaging from small laboratory quantities to bulk drums
