Product Overview

Orthophosphoric Acid 85% Extra Pure (CAS No. 7664-38-2) is concentrated phosphoric acid, a phosphorus(V) oxoacid characterised by stepwise proton donation and extensive phosphate salt chemistry. Its high acid content provides a practical reagent for reactions requiring substantial proton activity while retaining the non-volatile character associated with phosphoric acid.

The Extra Pure 85% grade is intended for general laboratory synthesis, preparation of phosphate compounds, catalyst and materials research and controlled acidification of preparative systems. It can function as a phosphorus-containing precursor and as an acid catalyst in suitable reactions.

Typical Applications

• Preparation of phosphate salts and intermediates
• Acid catalyst in suitable preparative reactions
• Phosphate-containing materials synthesis
• General inorganic phosphorus chemistry
• Preparation of acidic laboratory formulations
• Metal-phosphate reaction studies
• Controlled preparative acidification

Common Synonyms

• Phosphoric acid
• Orthophosphoric acid
• Phosphoric(V) acid
• o-Phosphoric acid

Storage Conditions

Keep tightly closed and protect from contamination and uncontrolled concentration change during storage. Use clean transfer equipment and reseal promptly after dispensing.
