Product Overview

Ammonia Solution 30% Extra Pure (CAS No. 1336-21-6) is a concentrated aqueous solution of ammonia that establishes an alkaline equilibrium involving dissolved ammonia, ammonium ions, and hydroxide ions. Its high basicity, volatility, and ability to coordinate with selected metal ions make it a versatile reagent for pH control, precipitation chemistry, salt preparation, and general inorganic laboratory work.

The Extra Pure grade is intended for routine laboratory preparation, synthesis, research, and educational procedures requiring a dependable concentrated ammonia reagent. It is suitable for preparing alkaline reaction media, generating ammonium compounds, adjusting solution conditions, and conducting laboratory processes in which aqueous ammonia functions as a base, complexing reagent, or nitrogen-containing reactant.

Typical Applications

• Adjustment of pH in laboratory solutions and reaction mixtures
• Precipitation of selected metal ions as hydroxides
• Preparation of ammonium salts and related inorganic compounds
• Formation and study of metal–ammine complexes
• Neutralisation of acidic solutions and intermediates
• Use as an alkaline reagent in preparative inorganic chemistry
• Routine qualitative and educational chemistry experiments
• Cleaning and conditioning of compatible laboratory equipment and surfaces

Common Synonyms

• Aqueous Ammonia
• Ammonium Hydroxide Solution
• Ammonia Water
• Ammonia, Aqueous Solution
• Concentrated Ammonia Solution
• Ammoniacal Solution

Storage Conditions

Store in the original, tightly closed, chemically compatible container in a cool and well-ventilated location. Protect the solution from heat, direct sunlight, and prolonged exposure to air. Reseal the container immediately after dispensing to minimise ammonia loss and preserve the stated concentration.
